Sponsor and sponsee both receive a share.
For each enrollment transaction of 1 STEEM, 2 shares are created. One for the person sending the transaction, and one for the person being sponsored. They can not sponsor themselves, so if the sponsored name is the same as the sender, we assign the second share to somebody else.
Some members get around this by coordinating with other members to sponsor each other (and we are fine with that).
thats great news cool thanks for letting me know!
