To request an import please phab>phab:maniphest/task/edit/form/7/|create a Phabricator task with a title of 'Import for [your wikis name]' replacing the name with a link to your wiki and attaching or linking an XML dump.

If it is a private wiki you can send this by email to sre@undefinedmiraheze.org.
