Hi wwwilson. You can get there by first enabling "use advanced settings" or something like that on the bottom of one of the subtabs when you go to Blog Settings -> pick a blog. I think it'll be the "Advanced" subtab, but anyway hit each subtab and scroll down - you'll see it. Once you enable that feature you will have two new subtabs - User perms and Group perms.

You will then want to use "User perms" to give User N the appropriate permissions on Blog Y. You can make each user the administrator of their own blog that way.

Don't use Group perms though unless you want all users in any given group to have the same permissions on any given blog. Actually you might find some cases where that works for you, but the basic idea here is to use User perms to make A user be the admin of A blog.

Hope it helps.

thanks but, I've been all through the site and can not find anything with use advanced settings.

Ops! found it in blog features, Thanks I'll check it out.
