I just made available a new style here at XenForo.com - it's the same as the normal one, except it's using the classic Helvetica font instead of the usual Trebuchet / Georgia / Calibri combination that XenForo normally uses.
Anyone like it? It's very clean, and emboldened Helvetica text is much more obvious than emboldened Trebuchet... Still, I'm not proposing a change to the default, I'm just trying stuff out
I personally find Verdana easiest to read but I'm really grateful for this theme because it's so much easier, even if it's not as easy as Verdana is for me. I guess it's a personal thing, but thanks for making this!
