We have the abandoned Meetup section on the left sidebar. Online campaigns on Roll20 can be started there. One reason we abandoned it was the risk of people organizing face-to-face meetups with strangers. But online games get abandond too and are slower to play than in-person table top games. 

If your interested in Running, while I hve never used Rolld20 or anything like that, I have used chat-rooms, skype, over the phone games, ect.  But I am willing to play in a game.  

I would love to run or play a gme on Roll 20. 

My schedule won't allow me to join another game on a regular basis any time soon.  But I would love to sit in on a session or two as a silent observer to get a better feel for the game.

I'd be up to joining a game on roll20. Although it depends what time you'll be running it. 

For those that are putting together an Online campaign... If all the players are in agreement, would you be able to some how stream it/save it? I would love to be able to watch some sessions and episodes of other people enjoying 7th Sea.
