It's my suspicion that it's the mods who choose the mods. That's how it works on most sites, except a few commercial ones where the mods are employees. I suspect, having been a mod on other sites, that lobbying the mods is not the best way to become one. Being a frequent, reasonably polite and level headed poster is. ---- Not suggesting that the OP is not polite and level headed.
