If your site is using invitations, you can now have the invitation requests sent somewhere other than
info@grasscommons.org (which was previously hardcoded onto the login page). To set an address add a line like this:
System.invitation_request_email = 'somebody@somewhere.com'
to your wagn.rb file. (Note, we're planning to improve user signups significantly in
Wagn 0.6.0; this has been due for a while now...)
