Lol I do setup forums for people, in fact i offer just about any service one could want; what I'm saying is that it isn't a difficult thing to use the template editor to add html code; in fact we've freely answered many questions here on how to do just that (utilize the language editor to change default strings).
I think that a good alternative would be to assign a "notice" css class, and assign it to any warnings, then have the default be say 16pt or something, then everyone can have their cake.
