Take a screenshot and link to it, that way we can see what you're seeing.
yes, that is essential - less talk, more see. ( <-- just for you, Pit!
also, enough bitching and moaning and whining - phpBB (especially v2) is the most customizable forum system i've ever seen. so far, there has been no template made for any different "accessability requirements" (i.e., the GIANT sized stuff in Windows), AFAIK - if you want to step up and make one, great! i'm sure there are plenty of people in this world that have a need for that. you are obviously one of them. in fact, i'm wondering how you even got to this page, since you are clearly legally blind and reading a computer screen is difficult for you. how do you "surf the web" at all?
at any rate, like i said - this is the most customizably forum system out there. it is also FREE. the first thing there makes it right for you - it's just not all gift-wrapped on a silver platter; the second thing makes any bitching, whining, and moaning just selfish.
don't like it? do something about it!
