Rp Tutorials

Okay, mods, what resources do you use to rally the troops? I've been in a few games where the mods do an amazing job at keeping people active with all sorts of OOC and IC activities, but sadly can't remember which communities I was in or what the hell the activities were. Are there any suggestions out there? A resource for RP team building activities? Are there any tips and tricks you use to keep your game active without major group IC plots?

Hope this is the right place to ask this! I'm looking to do random pairings for a game I mod and was wondering if there's some sort of online generator I can input the names in and it'll do the pairing up for me?
