I am the admin for a MW wiki and occasionally the need arises to delete a user or change their account info. Can I do this via Web- based interface, or do I need to edit the database?
Either the extension, or, if this is enough, you can lock the obsolete user for infinite.
Also, is there a way to send an email to all users?
You need an mail-extension, look for this at meta.mediawiki.org
