If you have the permissions set and enabled the option in admin chat options, you will have the option in chat menu list or on chat page.
@Jim Kingsnorth, plesae try to login. It should send another email. If you still don't get it, please send me a PM.
I'm having an issue where if a user is chat banned... but then that user's account is deleted... the chat ban remains on the chat banned list, and can not be lifted.
@ozzy47, on the previews version, only admins could delete/edit bot messages posted in the chat. Now moderators with permissions (delete/edit any) can do the same. That's that change that I was referring to and it has been done.
@Jaxel, will make some changes for the next release.
