altering the font is really easy, go and find whichever font you want to use in c

windows\fonts (if you're using PC), then copy it (ctrl+c) and then go to football manager 2005 folder in program files, then data folder then fonts. In there paste (ctrl+v) the font you want to use and then firstly rename the one called "fm main.t2k" to something like "fm main 1.t2k" and then rename the one you want to use as "fm main.t2k". don't worry about the message saying that changing the type of file may cause problems and do it, and then when you restart fm, it should be changed.
And if you knew all that and were just asking for us to be able to change the font in-game, then never mind all of the above and I would agree.
