- [x] A participant may give money to a Project..." this clause is the only mention of money in the entire document; other similar statements make reference to payments, not "money". Probably not a huge issue but maybe something to flag to the payments attorney, or just go ahead and make consistent.
- [x] "The Service is a platform to facilitate this agreement" - earlier, we say the Service is a platform to facilitate payments. I think we should drop/rewrite the first, since I presume this later, repeated phrasing about facilitating the agreement was tailored to address financial regulation concerns.
- [x] "Projects ... must be consistent" and "Gratipay reserves the right..." both seem like they should be in general terms, since they apply to other Collaborators as well, not just Project Owners.
- [x] The three sections titled "Obligations" should be retitled something like "Terms for Givers..." etc., since they contain things beyond obligations.
- [x] The Project is not a legal entity; would it be more accurate to say the agreement is with the Project Owner?
