My account is over 5 years old, and over that time I have gotten a couple of warnings. Is there a way to see what my past warnings were for, out of sheer curiosity.

File a ticket? Some warnings can be removed after two years (if not too serious), if you ask.

Okay, thanks! That's what I was wondering. :)

Yep, there are no other ways to know about dates/reasons of past warnings besides opening a ticket :c I wish there was a link from the user preferences page or something like that showing this sort of information (since it's more work for the mods...) but sadly there's not D:
