I use bold in my nickname and it stopped working for me one day so now all i see is ·# Tags such as (!IP) and (!WAT) are also no longer working. I tried uninstalling and reinstalling msg plus many times but nothing changed. I can still use plugins and the rest of msg plus features.
By the way, I'm using MSN 6.2 and msg plus 3.25
In the Contact List window of MSN Messenger go to: Plus! => Preferences => Instant Messages => Commands & Tags
Make sure "Allow the use of commands and tags" (for (!IP), etc.) and "Enable multi-format IRC style shortcuts" (for Ctrl+K(color), etc.) are enabled/checked.
Hack, hack, hack!
Finally became a Systems Analyst!
