I had an idea for a role-play awhile ago. It was basically going to be a group of people who'd struck silver out in either Kansas or Nebraska in the old west. Someone was supposed to have stolen the group's treasure and they were going to chase down the bandits. At the end of the day, it just didn't seem as interesting as I thought it was.
I'd just encourage you to go ahead and try to make an interest check. Tell you what, if you have an idea for a role-play I'll go for it. I'm feeling a bit adventurous and wouldn't mind making the effort.
I've looked around the website, and I haven't found a guide yet. In particular, I'm curious as to how to apply it to a role-play. On a single campaign can multiple people roll on the same campaign?
