I seem to have lost the ability to enter the Chat, it immediately boots me out.
Things to try:
1. Open it in a new tab instead of the existing one. This is the only way I can get in there.
2. Make sure you aren't in some kind of "private" browsing mode, have cookies enabled, etc. etc.
3. Check to see how often your IP rotates.
4. If you're using something like Tor, you should use something else.
