With user registrations enabled, we have found that when new users register, their primary blog is ALWAYS set to the admin blog--not the blog from which they clicked the "Register" link. For example, when a user wants to register for blog1.myblogs.com, he is sent to the registration page for myblogs.com (which is the main, admin site). After registration, the DB shows that the user's primary blog is myblogs.com, instead of blog1.myblogs.com, as was the user's intent.
How can we get this working properly, so the user ends up in the primary blog of choice? Or, must he first register under the "admin" site, and then sign-up for other blogs? Either way, we need a fix for this, and any help will be appreciated!
