As of today the Review a Host forum is closed for new posts.
There was very little activity in the forum, and from the activity there was it was always a question whether it was legitimate or people promoting their own company, as was also discussed in the thread Do You Believe in the authenticity of web hosting reviews.
The forum will remain to exist as a reference for a little while, but will be removed completely somewhere at the start of next year. At that point all threads will be moved to another forum for reference.
Host reviews are no longer allowed in any of the forums from now on.
We're going to launch a Hosting Reviews section on sitepoint.com featuring editorial reviews of top hosting companies this month as an experiment... people will be able to comment and add their own experiences to the bottom of the reviews.
