It appears that we have some problems with the login page. In particular, this is for those who use "name@domains.xx" (module "site_network". ) Error messages such as "Ole Martin@drupal.org" is reserved." and "When I try to log in drupalinorge.no (ask for new password and follow the link I get in e-mail) do I know that I've tried to use a login link for an account that is blocked." There are several types of error messages.

Even those who are running Internet Explorer 8.0 may experience problems. Solution to this (currently) is to run it in "Compatibility View" (you find the button in the address bar). Or in Firefox / Opera, get it all right.

We don't have this problem on http://drupal6.drupal.no (demosite in progress) so the error is only here (http://www.drupalinorge.no). 
Suggestions?
