I don't think my one year of computer science could teach me anything that could help you in this goal, so good luck!

Heres the idea:
The sig lets you upload an image using a url. Id have to make a url that hosts a random image every (unit of time). Id also have another url linked to the image in the signature that redirects to the corresponding tfwiki page as the image (and changes in sync with image url). Id have to find a way to make the url's but the programming wouldnt be super difficult.

Well the wiki itself does that right? Every time you go to a new page it switches, so logically if you were able to access the wiki's code, you could possibly find the code and copy-paste it? Maybe?

Uhuh, I too was once a victim of it...but I was drunk that day.

oh no
