I used to be a mod, way back in the day. Got banned for saying a website... But yeah. Basically theres a place to see your recent bans and how succesful they were, you can see your recent mutes, and there's a link to special forums especially for mods. Theres a suggestions forum, a mod lounge, recent update forum, etc. (Mod only forums). It's nothing special. PMods are way overrated. All they can do is mute people and have first priority bans. The plus side is you can get direct communication with a lot of JMods. You can view a list of all PMods, see whos new to the community, etc. Also, I never attended one of these while I was a mod but once a month or so they hold "Surgeries", which are in-game meetings (always F2p worlds) where they discuss in live chat whatever they plan on discussing ahead of time in their Forums. These Surgeries are held in extremely unpopulated areas of really unpopulated worlds. If a non-mod appears to a Surgery, they have to log out and find a new world and location. PMods can suggest locations/worlds in their forums.
I really was a mod in the past, I'm not making this up. Any real Pmod can confirm this if they'd like.
