The TalkRadar Community have fashioned themselves as "TDards." The group is very active, posting many times in the GamesRadar forums.
A good amount of TDards, have twitter accounts which you can follow. TDard Twitter list
The third segment of the podcast is the community segment. This has been the case since TalkRadar 18, when Question of the Week became official.
More recently, TDards from around the globe have united to create a weekly fan play session, which is formally known as "TDard Saturday". The sessions usually take place on Saturday (but can happen on Sundays too) at 12:00pm Pacific, which is 8:00pm GMT. The game played by the TDards is chosen in the forum thread or can be found on twitter using the hashtag #TDardSaturday.
