It occurs to me that I might be interested in starting a new group altogether or at least pitch out an interest check in a new group idea. And it might not be a great idea to try to pitch that in my old group thread. Would it be okay to pitch an interest check on this new group even if it used a similar game mechanic as the previous one? Different game idea, but the same system (a la D&D, d20, etc).
What is okay in this regard and what isn't okay?
