...What is the best way to get a standard Tahoma font working, this is assuming it works standard on all software. Which in turn, I assume xenforo recognizes Tahoma as a font.
Jake, I'm sorry if I seem like I'm trying to go around in circles....but I'm not.
Here's the settings I have for Tahoma on a MVC3 site...
A part of me feels like it's not really Tahoma. To me, the settings I have for Tahoma on the site makes me feel like I saved it as Arial.
The only problem I have now, is that when I added the font family to the body properties, it wouldn't cover the postbits. Ya know the posts themselves. See for yourself.
I would suspect then the font used for posts is listed in a separate CSS Stylesheet used for it. I've not messed around looking further into XenForo on the styling side of things because I use the default theme and will be sticking with it. But have spotted there are a number of different CSS style-sheets listed under "Templates". Filter them out using the keyword "CSS". Then I would take a look at some of them (perhaps)?
That would be my guess, looking for font styles used in them.
