I'm sorry to as such a basic question, but how do you create a subscription box. I'm looking to make one almost identical to the one located on the upper right of www.thanksrp.com.
Any ideas/suggestions? Or, do you know anyone that can do this for me on the cheap? Thanks.
If you sign up for an email marketing service like "Constant Contact" they will provide the code. Otherwise you could use an email form and you could maintain your own list.
You actually need some back-end code (PHP, ASP.NET, etc) to handle this type of thing.
A service like Constant Contact (as eruna recommended) is a good method for handling these type of processes if you don't have a strong programming background.
Even if you do, they can still be very good (the medium-sized company I work uses them to send out a monthly-ish email blast to about 40,000 people with pretty good success).
