So my intent is simple:
Multisite has a form for "Register" which creates a Subscriber Role
Then another for "Join" which has a payment condition, and creates a Contributor role.
So can registration update a username/email profile role, not just create new?
What would happen if I used something like this telling it to ignore users:
Would it still update the Role on the subsite regardless of duplicate email, or would it create extra emails?
What about concern of dummies entering multiple username variations? Email is constant, but username could be an error. will it make multiple accounts under that email/username? I could see that becoming a problem
Is there any ajax/js we can add so when they tab out, it queries the database to see what the username is for that account? Or do i not need to worry about multiple usernames under 1 email address?
