Thanks, this is an exemplary answer, not to mention lightning fast as well!

I would consider if Wiki had at http://xfs.org/index.php/Special:RequestAccount page:
* Privacy policy http://xfs.org/index.php/XFS.org:Privacy_policy
* Terms of Service http://xfs.org/index.php?title=XFS.org:Terms_of_Service&action=edit&redlink=1

The latter being something I must read and agree on before I can request a user
account.
