You may or may not see this message, but…

"Undo revision by $1" (or something similar) is probably a MediaWiki message stored deep within the default files of every wikia, including ours. It appears as the default message whenever a user reverts someone's else's edit. $1 is a variable that is automatically replaced by the name of the user whose edit is being undone.

I don't remember whether IPs can undo or not, but it is basically just undoing an article to a previous copy, or revision.

k?
