Since we don't know the revenues from them we have to guess:
If they are the full $15m (they aren't) that's roughly $4 per user each month.
If they are closer to half of the revs that's roughly $2 per user.
If they are closer to the $1.4m number in the 8 that's roughly 40 cents per user.
All we know is it isn't anywhere close to $10.
We have to wait and hope that the S1/A answers this most critical question before we really can make any reasonable positive projections, and they clearly won't be based on $10 or probably even as high as $3 per user.
