First, how are you editing ffa1, are you in Radiant or are you using Lugormod or an in game editor or what? If you are in Radiant, you can make a brush, make it a trigger_multiple entity, target it to a target_print, and then add a "message" key to the target_print with a value of the message (and no quotes, they'll cause errors), but I've only ever edited in Radiant, and only know how to place money dispensers and jail in lugor mod.
Problem: Message Button in MP.
Linear Mode
