Fortress Forever has
no guides on GameFAQs.
GameFAQs is probably the biggest source for simplified, text-based guides for games. They do indeed accept guides for mods, as Quake TF and TFC are both listed.
We need a good quality guide written here, and a dedicated few of the forumgoers here have written guides of their own - even if it is just a copy/paste
of your own original work, it would be good to have a guide hosted here.
