Well, in addition to the new rule with players needing to have the responsibility / initiative to keep up with the RP and know when to post themselves I would prefer people be interactive to the point that they are not “lost” to the flood of posts that could happen at any moment— players need to at least post weekly at the bare minimum and take it upon themselves to engage themselves with other players. 

As for additional characters, it’s pretty much the same minus the NC parts. I will be more lenient on bios not being too developed, but there needs to enough to have a point of reference from. Before I became a big old GM for NCQ Katarina Poux was a side character I made, so she serves as a poignant example.

Also being active in the chatzy is probably a big plus.
