just set the ui_motd onconnect for clients and itll show in the menu.

I don't think you are grasping the issue - there is no code in the 1.0 gametype scripts to open the server info menus. So, setting a dvar - ui_motd - is not going to accomplish anything because there is nowhere to show what the cvar says (no menu open = empty space).
