For a moment I thought maybe you were just a little person.
There are a lot of folks here who use a number of VTTs as well as a few developers of such so you should find good useful information here.
I want to use a VTT but so far have not mastered one. That plus, I'm too busy being artistic and creative in my free time to actually sit down and work out how to run one. "Soon", I keep telling myself.
edit: Oh, and welcome aboard.
