As this raid signup system can be a bit annoying to sign up for, here's a short explanation about what to do:
1. Create a forum account and log in on the forum.
2. Click on Profile, and then create your character. Select your race, class and gender. Enter the correct name and level. The resistances are nice to have, but are not required to be filled in.
You're now set to sign up for raids. Click on "Main Page" to see an overview of current raids and click on the name of the raid to sign up for it. Please always sign up as queued. The DPS officers will create the group based on what classes are needed, before the invites start.
