That message ("
you are banned from using this forum") should be edited out. It serves no purpose whatsoever other than confuse people. Imagine how many msgs the Meta sections would stop getting if that sentence didn't exist.
Suggested solution: omit the "you are banned" and write only this:
Sorry Guest, for security, your account has been locked. Email xx
This should be the message that pops up when an actual ban wasn't enforced. @Theymos or whoever's in charge of changing forum features and messages should consider changing this.
