I've added a way to change the default timezone when viewing games, so now it will show listings in whatever timezone you set in your preferences. You can change these settings (including whether the sidebar Flash chat shows) on the lefthand sidebar.
I'm going to add a player listing, which will allow people to simply specify the dates and times they're usually available. This way, if someone wants to run a game, information for locating the players will be easily available to throw something together. If there any suggestions or requests, please let me know at email@example.com.
