One of My fonts isn't displayed in all Caps, even though another is, and I want both of them to be caps. I don't know how to change it, and I'll do almost anything to change it (it really needs to be in caps)

Even though you didn't make it very clear, I believe you are referring to the text display banner with the name of the font Apacaxi Comic.

The default display uses the same case as in the font's internal file name.

Send a private message to the DaFont webmaster: http://www.dafont.com/profile.php?user=2 and the banner will be changed, eventually.

Thank you very much
(I thought it would be kind of cheap to include my font in my question, so sorry about that).

The fastest way to make that happen is changing the name of the font (not the file name but the font name) in all caps as you did with your ABNORMAL font and then submit as an update, explaining the update and why to the webmaster.
