This plugins allows admins to rename or copy users on the local server. By default Openfire does not allow to rename users because the username is the primary key in database. This plugin creates a new contact and tries to copy roster entries, groups (including shared groups), properties and vcard from the old contact to the new renamed one. If you want you could keep the old user as well.
Copy justmarried.jar into the plugins directory of your Openfire installation. The plugin will then be automatically deployed. To upgrade to a new version, copy the new remoteRoster.jar file over the existing file.
The Just married plugin can be configured under "User/Groups"-"Users"-"Just married".
