If there is, I want it removed.
The MOTD is shown to you for a REASON. I ban people on my server for not reading the MOTD.
There’s currently a crashbug in GMac that kills the program any time HTML is encountered, hence JoshJosh’s question. I’d suggest server owners look into setting up a plain-text MotD of some sort (you could use a Wire text screen in front of spawn) until the patch to fix this is released.
