Played around with Tabletop Forge tonight with one of my face to face gamers, Brian. It is still in Beta but works pretty well. I use Chrome and everything seems to work fine but Brian was using Firefox on a wireless router and had some difficulties. I like the grid overlay and the ability to import maps and tokens. My only complaint is that the chat and die roller are in a separate window instead of along one of the sides.
I'll play around with the macros next time I try it.
