== Cross-wiki ==
Hat collecting can occur across wikis, with users using the rights they've got at one wiki to bootstrap an application on another wiki. This isn't always a problem: most of the user rights require trust. If a long-standing Wikisource admin turns up, there is a good reason ''ceteris paribus'' to presume trustworthiness compared to a complete new user.
But remember, some wikis are very lax about handing out user rights. [[Simple English Wikipedia]] have been known to hand out rollback after two edits... on the basis that the user also had rollback on Commons. Be careful not to replicate this at English Wikipedia.
