Sightings in no particular order:

Aiko
Mez
Poison IvEE
Salamander
Dreama
Tweety

And of course Monolith, Disguise, Shadow, Dethman (#jj2 only though), Cobra/Ninjapixie, etc... but those are still #jj2 regulars.

Nevertheless I really enjoyed this bash, even though there were quite some problems surrounding hosting (PURPLEJAZZ TEST YOUR PACK NEXT TIME). n00b summarized it nicely (PITS+HELLDOOOOOOME+CRASH?=Bash).
