Bukkit

What is the enhancement in mind? How should it look and feel?
Since you seem to be putting work into making the filter pick up on many more things than chat, I have a suggestion: Give the power to filter usernames. On player login, check their username and put it against the filters.
For example I might say to match the word "fuck" in a username and "then kick Your username is innapropriate!".

Please provide any additional information below.
While it could be viewed as a bit mean to be blocking whole users from joining since they can't change their username, in the near future they can and I can imagine people changing their usernames to more rude things just for the hell of it.

This will be part of 4.0
