I wanted to make an edit on WikiMeower, just to see my name got stolen. 
Just use another username
Maybe XPaut0, XPautoWasTaken, XPauto1, etc.
I don’t use XPauto anymore, but I will apply the same thing to my username.
WikiMeower uses the same accounts as the rest of Miraheze, which is the current software used for WikiMeower.
I’ve signed up for another Miraheze wiki, but was also able to sign up on the Meower one, so I don’t think that’s true
It is true! WikiMeowers uses the same accounts across all other Miraheze wikis.
