The game mode sub-boards have been merged into this section. There's now a prefix added for the modes, along with a tag for [Game] for general game discussion, [PC] which is obviously for PC specific things,  for 360 specific stuff, and [Other] for the things that are somewhat related to the game, but not actual game discussion..and stuff that just doesn't have a good fit with one of the other tags.
I've tagged the topics that were 1st page of the former sub-sections and a bunch of the TM general topics, but not all of them. If your post is lacking a tag, edit the OP of your topic and then select the proper tag from the dropdown.
Prefixes are also now available in the TV, Music, Etc section. Again the 1st page is already tagged. See above.
And yes, I realize this is in the wrong section. I did it on purpose so that it's more easily noticeable to the relevant section and will move it to Site News when appropriate.
