Submitting Common App recommendations

<p>I've sent an invite to my teacher on the Common Application and she's agreed to fill in the online recommendation form. But she recently told me that she can't see any option to submit the recommendation online? I searched the issue up a bit and found out that the submit option doesn't appear until the 'profile' of the teacher is complete, but I'm not sure what that means. Does the teacher also have to have an account on the Common App to submit recommendations? Please help!</p>
