Thanks for the description. Maybe that thing can be put into the description somewhere, too…
BTW I know others on Liberapay, which have a " <projectname> community" (e.g. “SecureDrop community”) account there. (maybe in addition to the one for the core devs/core fundation/whatever it is), which may be a way to go.
Also Liberapay can be used for distributing money in the community at least. As people may be verified (as contributors) and added to the team. The downsite is they can take out as much money as they can, but well… somewhere you have to trust them.
Currently you have one personal account in the team and one, which seems to be more or less the community thing. This rather looks like centralization, considering I have no idea who runs that one account. (And BTW, it’s possible and not bad to do so, if you e.g. have one account for “hardware costs” or such stuff, as Liberapay itself has it, but it should be clearly labeled.)
