Looking for active/mature/open minded PvE guild

Hi all, I'm newish to GW and sick of PuGs. I'm a mature, very open minded player with two RL friends that play and are also looking for a good guild. We're nearly done with Proph (I have W/N) and started on Nightfall (Me/Ele), and we're playing through the PvE stuff.

Just so you know: we are adults with jobs and stuff so we only play like 3-4 times a week for a few hours. We all use TS but could use Vent obviously.

Also, one thing: from what I can tell this is rare among players but I actually do like a challenge =). I don't want things handed to me and people to just walk me through everything. Working in PuGs has been a challenge but mainly because people just blunder into groups of 10 mobs and get themselves killed . Not the kind of challenge I was looking for.

Characters are Takara Sandral or Takara Kretz.
