You edt it, and there is this little tab on the side (near the templates called Categories. If you click on it, it gives the list of the page's categories. If you hove over one, there is a penicl (meaning editing it), and a trah can (to delete it). Click on the trash can.
On the Recent Activity page, it said that you had edited my page because it wasn't mine. Now all my previous edits are gone. :(
However, this is all just a misunderstanding. Allow me to explain.
I am the owner of 5 Nights at Freddy's Ultimate. At one point, however, I wasn't on the wiki for quite a bit of time, and when I came back on, I had a different contributor number, that's all. There was no need to remove my edits.
Please don't take this as the beginning of an argument. :(
