Is it possible to form a town of secondaries?

[Mark]

I'd say the answer would be that you're free to start writing about the town and then if you feel it's getting big enough, that topic can be broached. I can't really give a definite answer beyond that, as it will depend on how 'big' (both as an idea and in population) the town gets. I'd say drop a topic in the Omniverse Discussion forum and see who is interested first, though.

As for Staff Participation, that'd be voluntary for whoever among staff would want to write with your group. Beyond Omni himself, there are not that many (none that I can think of, though I'm sure I'll be corrected) Site NPCs that are controlled solely by anyone in particular.
