Oh, also, at the top of the Forums page there's a What's Happening in the Community Today section with a list of chats.

If I click on a particular chat it's supposed to give the times but the one I clicked on seemed to be showing info from a week ago (2/10/2010).

The time zone information isn't entirely clear. Every Forum page has a note at the bottom saying (for me, anyway) "All times are GMT -8" but there's also a note at the chat listing saying "The times shown may change, depending on DST settings". I'm sure if I attended those chats a few times I'd soon figure out the time thing and those notes would make sense. If I were planning to attend one for the first time, though, I'd want to confirm the starting time.
