Thanks for the input !

For the delegation by sponsors, it's planned, as it would alleviate us in terms of SP needed to be delegated. And great idea for putting this as a scoring variable, it should incentize sponsors to delegate at least a portion of the 15 SP to their affiliates. Even if not the full 15 SP, 5 SP by sponsor is already a third less and on a lot of accounts, that will quickly amount to big SP savings.

For the OAuth verification, could you please elaborate a little bit, as I think it's a promising idea ? It's just that I'm not sure I understood completely what it is about (I know OAuth, but didn't quite understand to which the site they plan to use you're referring to). Do you mean making a verification like system as we do for account linking ? Or something else ?
