Nice work again. One problem we face in other software is that when moderators auto-ban a member for a week (after reaching x points) it's not always clear for that member that they can't register another account to keep posting. So it would be useful if a default message would be automatically shown to any temporary banned member saying they can't register during the week they are banned, and doing so will result in another warning or even permban on their regular account. I didn't try it yet on the beta, so would this be possible in this system? If not, consider it a suggestion.
Another thing is, our moderators want to stay anonymous while giving warnings (including the PM), because some people bother them personally sometimes outside our website, so is this possible? If not, I would also like to propose it as a suggestion.
An automatically created 'discussion thread' in the moderators forum about the warning is also something we find very useful.
