(I can't make category links, they always end up becoming blank spaces) For category links, e.g. Category:Article stubs, you should add a colon before the Category bit like Category:Article stubs instead.

Essentially, what seems like a blank space is treated as you having added the category to the thread (e.g. if I write, this thread will display as if I added Category:Tracks to it.)
