If you have complaints about GMs you can join the Public Developer Channel on IRC:
server: irc.freenode.com
channel: #planeshift
Speak with anyone who has a @ or + beside their name (look for Vengeance primarily; he is the one who deals with GM issues).
Whatever you do, do not use the forums to voice complaints, because they do not belong here. Those will be deleted.
When speaking with Vengeance or any other dev about the problem, give as much information as possible, and provide chat logs that can back up your claims. Chat logs are located in your PS folder\'s \"logs\" directory.
