Okay, so, here's my two cents on the table. We don't know what happened with Martian, but I have run into situations in the past where GMs have flipped the table and deleted everything when their thread got hijacked. Not here, but on other places.

I would consider making a new thread, so the new GMs keep moderation tools, and put enough of a spin on the original idea so that there's not [i]as[/i] much drama if the OP comes back. Basically a non plagiarized OoC post that's still compatible with the current cast, with minimal edits if any to character sheets. I'd be willing to help brainstorm on this if needed. Co-GM is a lot less pressure for me.

This is just my take though. Don't smite me please.
