Right on and welcome to the guild. I've just started into making VTT maps myself and want to do more. I have not put the time into figuring out Maptool yet however although I really would like to run some sessions myself some day. Hopefully I'll get around to messing with it. I want to get the lighting/vision settings figured out so I can see what it will look like from the players point of view. That is hopefully, my next step.

Anyway, as Torstan says, just post and there will almost always be someone nearby to help out.
