In the forum:

How about the option to change the order of the posts from chronological to reverse chronological order…

Give us the option to receive an email when a reply is posted in the forum or the main site too… whether it is a post we started or one we are active in, or just want follow a post.

Make the reply text box be a percentage of the width of the page or container instead of making it a set number of pixels wide, that way it will grow and shrink depending on the users browser size and such…

The main site:

I liked the site the way it used to be with the featured/newest article on top and the other articles in a double column below with the rest of the articles.
