I'm recommending these today because I found these very, very useful. Here's what would be implemented.
- ChatTags is a script that enables users to customize their messages on chat. They act like HTML tags and are indicated by square brackets, "[ ]", similar to BBCode.
- WordFilter is a script that displays an inline alert to any user who attempts to post a blocked word into main chat. The user can then choose to continue to post the message, or choose to cancel.
