Pick a time tomorrow that you're able to come to Voobly and I'll see if it works with my schedule. If not, we'll shoot for another day/time. One way or another we'll get you hooked up! ;)
Edit: If you find yourself in Voobly and I don't answer in the main, shoot me a IM. Sometimes I'm at the computer, but heavily immersed in something else so I don't know know what's going on in the main.
