Unfortunately fiddling with the fonts/colors in the post displays doesn't just adjust the fonts/colors there. I learned very early with this theme that trying to adjust the post displays causes even bigger problems elsewhere, so I'm afraid we're stuck with things the way they are. However, that doesn't mean that individual members can't make the forum display differently in their own browsers because browsers allow for font size adjustment, so it's possible to make the text larger by adjusting it directly in the browser. Firefox even allows for adjustments on individual pages/types of pages that don't affect any of the other pages/types of pages on a Web site. And if worse comes to worst, members can switch to a different theme by following the instructions in:
Choosing A Theme
(Though I wouldn't suggest choosing the "Variations on Blue" theme, as was the case back when that topic was originally posted. Nowadays the best bet is to use "Midnight".
