User blog comment:Sarah Manley/Updates to Wikia Chat/@comment-3030984-20120508055615

Right, just to clarify for everyone currently on a ban:
 * When your wiki switches to the new chat system, your ongoing ban becomes a 6-monty ban that is automatically removed after that period.
 * Although the 6 month change is automatic, that doesn't stop it for being shortened (or lengthened) by an admin or chatmod.
