Features that I like.
1. ability to see who posted in the last 24 hours. Its easier to see who posted and to what thread.. rather than having to open a thread to see who has replied lately.
2. at the bottom of the threads there is a "jump to" box.. where you can select which forum you want to go to or back to the one that you are in.. prior to the upgrade you had to scroll back up to the top and click CCB.. (now its Main Index)
3. its nice to see how many people are on line and not have to check 'who's on line' at the bottom left of the Main Index.
4. the 'emoticons' smiley faces seems to be very popular with many posters. They do seem to let the emotions of the poster show thru a little better
5. the 'spell checker' is a good addition as well..
