Don't know if you folk around here know about this but GOOGLEs GMail service is now offering a FREE phone service.
Well free at least until 2011 and anywhere in North America.
If you have a working mike, and speakers/headset, this will work. You can call ANY phone number and the sound is great, no delays.
I tested it calling my wife at home from my puter and it worked great.
Then I called a clan buddy in Arkansas just today and he was very impressed by the quality.
You do need a gmail account, so if you don't have one I can send you an invite. Just PM me, preferably over at the TLB forums (gotta encourage internet traffic ya know) and I will gladly send you one.
