How To Strip Comtitles in PennMush
It does seem to be admin level, and whilst I staff on the game in question, I'm clueless with code.
charformat, alas, is also a code-y thing. It's just one you can set on yourself instead of channel-wide.
If you're admin and just want to turn off comtitles completely without fussing with code, just set the channel "notitle" as @Bobotron said above.
