I've always been very shy and introverted in groups... one on one, I'm less shy, but on vent, well, I just sort of took the plunge a few weeks back and forced myself to talk and get used to it... >.< even now, its hard, but its getting smoother, I suggest trying to talk with one person on vent, then working your way up to squads and the like, that's kinda how I did it and I feel much better about it than I did two weeks ago.
