There is the "Guardian" channel and also the "Looking for team channel" you can try.
I can, if you'd like, pop your global off an invite to "Guardian's Team" (or it's Guardian's TF, not sure which one I'm mod of) for ya. Invite will come from my global, same as my forum handle. Also, as Ariel said, the "Guardian" channel is good for chatting and team finding.

thnx all
wow, I joined Guardian and Guardian's Team channels and there is nothing on either. Guardian is just ppl talking when there are ppl on, and there is not a mod for GT to unsilence anyone.
I have got my stalker up to lvl 26 and have yet to get on a SF. I have tried to form one and watched to see if any were forming, but it is dead here......
I have no idea what you're reading but I pick up most of my TFs through Guardian. 
Redside is a little more quiet but rogue alignment can help that.
I'm not on US-time; I'm usually on my way to bed as you guys are getting home from work.
It's not dead here. Get on a few teams, get on some globals and you'll find out about the TFs even before the few remaining spots are advertised in channels. There's quite a few TFs listed on this forum in advance too.

There is a Level 50 Channel that is serverwide. Most people in channel play on Guardian Server (but are by no means required to be on Guardian to join, just have at least one level 50 on your account).
There are constantly people looking to start TF's and Trials, and if you don't find someone starting one up just mention you'd like to run one and you'll be suprised how many people respond.
I am a Mod on that channel, shoot me a tell at @Tex Mech and i'll bring you into the asylum with the rest of us.
16 Level 50's currently spread across several servers.
anyone know of a server wide channel for TFs and stuff?
shoot me a tell @Envoy of Shadows if u do plz.
