My personal suggestion would be for Tobiax to create the OOC post anyways as the creator of the tabletop game, and promptly make Iatos co-GM. I don't see how splitting the responsibilities 50-50 would do more harm than good. Tobiax can handle the system, Iato the other story.
@Iatos@tobiax This is also a fair option (forgot about the Co-GM option but gotta play it cool)
There are many ways to go around this problem (and if you indeed ARE going through this debate in PM, sorry for the bother but I'd lack such information to make other deductions than this seems stale)
If it makes your hearts any warmer Co-GM has the same rights as GM over anybody else really (as far as I know) but can(?) be got rid of if need be (not to insulst or otherwise down value @Iatos)
