What other communities are you a part of?

Hello there, if you are here, then you are most probably part of the Mann Co. Gamers group founded by my friend Jakob.

But, if this isn't your main group, or if you are part of another group, then post below what other groups/communities you are in.

I am in:
Ace Fortress 2 (My main one)
Here (close second)
Pro TF2
JustAwesomeGaming
Skial
Hellphoria (this one is my MapleStory group)
TF2 Outpost
Fair Honest Trading Samurais
TF2 No Bullshit
HmX Gaming
Multiply a Weapon's stats by 10: The Server

Steam groups that aren't much communities; more like collections of friends:
Tootis-Pootis's Professional Pootises
People who hate the Seventh
Let's all eat watermelons under the Eiffel tower!
We Want Bragging Rights
