It seems that Community Central's new Forums are broken. The replies to a thread don't show up when I look at a thread. If I examine the history they are there, but I can't read them until several hours later.
If I reply to a thread, my reply may be outdated by several hours, and I wouldn't have bothered to reply if I could read earlier replies that do the same as my reply, or better.
Using Purge does not seem to update the thread display either.
