If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
Presumably for a rule violation, but I'm not sure what. There's no record of it in the staff forum member issues area (where we keep track of problems) or the GM forum ban notice thread.
If you get on the IRC server and send me a PM, I'll unban you.
You might not have been banned, I did do a lot of banning of a certain pain in the rear a few weeks ago so it's possible you got shackled with his address after the network had a restart.
Sadly, unless you can tell us what your mask is, it's not going to be easy to check. You can find out your mask by doing a /whois on yourself.
Edit:
Nevermind, the banlist was wiped. If you still can't get in, then it's on the networks side (talk to Chaz or JC)
