A quick response to the VT fiasco. I have been in the beta for a few weeks now, and while not perfect, it has been quite fun and useful. While not as robust as Maptools or Fantasy Grounds, it has been fairly easy to learn and game with.
Its not free like Maptools (I believe), but is not nearly as complicated to use. And for those who have a DDI subscription already, it could prove to be a powerful tool for those who have no access to RL games, or like in my case, have RL players who can't seem to make plans to get together one night every week or two.
