The "Right Column" which displays the Profile, Threads, and Messages, seems to work better (more precisely) on my slower XP computer than on my newer Win 7 computer with the i-7 920 CPU
Yep, it is slow and you can't search posts. When you post and then there's a link to choose 'all of your posts' but then it's not in chronological order. There's also the most recent posts but there's posts listed at the top that were from two or more years ago. Maybe the programmers don't care?
Well there are some recurring problems with the site, but it is no longer slow for me, and hasn't been in a while. Try clearing cache/cookies or try a different browser or something. Also Adblock Plus and Flashblock help.
