Well The King’s English is quite helpful too. Recommended site.
Good Luck
For fiction join a critique group. I’m a member of [U]CritiqueCircle[/U]. You not only gain when other’s give you feedback on your work, but you gain by giving feedback on their work because it teaches you to look at things critically.
Sure, if one writer takes the even chapters and the other the odd, or some other back-and-forth division. However, if they take different tasks it could turn out quite well. First, they could brainstorm and design the characters and story together, then the one who is able to quickly toss a manuscript together could do the first draft, and they could go back and forth on the editing passes. In addition they could each write dialog for different characters. It’s common for beginning writers to make all their characters sound alike and this would be an easy way around that.
It doesn’t have to be a disaster of style. IMO a bigger problem is one writer becomes a slacker, but sill wants their name on the piece.

yeah I agree with PC101, reading more and more will help you improve your grammars. Even me I also have those grammatical errors 
by the way no one is perfect were only humans.
When composing entries, I use MS Outlook since it has a spelling and grammar checker. Then again, it’s also important to re-read your draft before publishing. And as a guide, if something doesn’t sound right, then there something wrong with the grammar.
Just hope I could still add something. I am a big fan of this blog and I am learning so much. I hope this can help somehow.
Thanks!
Ask somebody to proof read your work
I say “new” because the site has been around for awhile. It’s just new to this thread (I think 
).
sofware is not sufficient for you watch out you grammar books again
I have never used the different programs but I could probably use there service. I have just done spell check and reread the blog as well before I add to our site. Have only been at it for several weeks so learning. Rereading has actually been the best advice I could give.
Use MS Word, and trust that the little green lines that are pointing out grammatical mistakes are accurate. After fixing enough of them, you will improve…
This is the best I’ve found… I actually still have a dog-eared copy of “The Elements of Style” from when I was in college.
The Elements of Style (online): http://www.bartleby.com/141/
The Economist’s Style Guide: http://www.economist.com/research/styleguide/
The Economist Style Guide is a concise, readable and surprisingly entertaining guide to good business writing. It is arranged alphabetically and covers topics from Abbreviations to the correct usage of ‘while’.
The generally terse guidelines offer little room for literary fireworks but they are clear and precise. This is what you want from a reference book.
Your plea for help with grammar is an increasingly common one. It’s interesting that so many bloggers and Web site owners are feeling the pressure to use proper English when they write their posts or Web content.
And well they should. Grammar, punctuation and usage errors reflect negatively on a writer’s image and credibility. Like everyone else who writes anything that will be read by others, bloggers and Web site owners shoot themselves in their collective feet if they write poorly. Then can have the best information in the world, but if they present it in a way that screams “uneducated lout,” people will question the value and integrity of the information itself.
So where do you go for help with grammar? There are tons of books out there in printed and online formats. But my experience is that they tend to be chloroform in print. And you have to read through endless pages of rules to find the ones you actually don’t know.
Another problem you face is that you often don’t know that you don’t know certain rules. For example, I spent years as a full-time freelance writer putting hyphens in phrases like “the book was well-written” when I shouldn’t have used them, and not putting hyphens in phrases like “a well written book” when I should have used them. (If you’re confused, you can read a full explanation of this issue at http://thewritersbag.com/writing-rules/well-written-or-well-written.)
In my years as a working writer, I’ve noted the English rules and issues that people are most likely to get wrong when they write. I’ve addressed these in what I hope is an easy-to-digest, straightforward way in the “Writing Rules” category of posts at http://thewritersbag.com. It took me years to cull these out and make sense of them. I hope they can be of use to you as you work to improve your writing.
Hope this helps.
PS. I compiled the 50 most commonly abused rules and issues into an e-book (http://thewritersbag.com/e-books/50-must-know-writing-tips-for-the-real-world). I’ve found that if people learn these, they will eliminate almost all the mistakes writers commonly make. And they won’t have to pour through hundreds of pages and thousands of rules to zero in on them.
Great resource. I like it most.
Reading increases your vocabulary. Reading exposes you to different styles of writing.
If there is ONE SPECIFIC advice to give…it would be…be a voracious bookworm.
Also you may use “English Grammar In Use” written by Raymond Murphy.
I have to say that Strunk & White remain the gold standard for grammer and useage, at least in my book. I’ve been writing (fiction and non-fiction) for at least 10 years, on and off for various companies and myself, and nothing beats their no nonsense approach. The site I use to read it online is

which has already been posted I think.
My personal favorite passage, and on I always need to re-check is rule number 12
Put statements in positive form.
Make definite assertions. Avoid tame, colorless, hesitating, non-committal language. Use the word not as a means of denial or in antithesis, never as a means of evasion.
It’s never a good idea to speak in writing in a passive manner… hope this helps a little bit.
