this is really grat plugin :)
I have web with 700 users who time to time publish posts. I run WPMU with 17 subdomains.
1)Sometimes I need change the user role from Subscriber to Contributor or Author. If I would like to do the change, I should go to each web (17 subdomain) and chance the role.
I thint this could be done in network admin menu automatically for all subdomain, or to have a possibility to choose subdomain.
2)I look for feature to count the posts/comments of the author from all subdomains. Just simple counter how many post have this user published on WPMU.
What do you think?
