If there's a problem, type !report and report a user or spray. Say SEAPONIES for general admin assisstance. Don't call for one admin in particular, as it varies who will be around. If there's an admin problem, e.g. you get kicked and don't think you should have been, post about on the forums. BUT DON'T BE A DICK. Yes sometimes admins make mistakes and it's fine to be angry. But being a dick about it isn't going to help your case.
For more info and pony community fun stop by the forums!
