i guess that comes down to personal preference?I think the font size for the default forum theme (Panda Dark) is too small.
font in general or something specific?Maybe it is, maybe it's something that affects a lot of people that needs addressing. For me, other XenForo sites have slightly larger text and are more comfortable to read. Since I know that extracting feedback from people can be like getting blood from a stone, I'm giving you mine in case other people feel the same. If not, then at least you know it's probably not an issue.
