[okfn-help] problems with adding users to new blog bigclean.org

[Daniel Dietrich]

I am trying to add people to a new WP miltisite blog 

bigclean.org

I think the way to go is by adding people via
http://okfn.org/wp-admin/users.php

Now I can't find 

Jindřich Mynarz <mynarzjindrich at gmail.com> with user name:

jindrichmynarz

Thats weird! I can find Jindřich here:
http://okfn.org/members/jindrichmynarz/profile/public/

Hmm, any ideas?

Daniel
