User blog:TObUsCuS101/Templates... Help?

The Story:

I was venturing through one of my favorite wikis, second only to this one (of course, it's the MSPA wiki :P) and I saw all sorts of templates that I wanted to use on this wiki, but the templates contained within the templates (Wow, Templateception...) weren't on this wiki. It kind of made me sad, so I took to here to ask a few questions.

The Question (sort of):

Are we wiki users allowed to upload our own templates?

(I've actually been wanting to ask this question for a long time, I just couldn't figure out how to word it.)
