None of that is “informal” use and implies close association with the OSMF, if not vetting by it. In practical terms that boils down to a contract with clear rights and responsibilities with somebody/something having to be in place (as with any kind of affiliate scheme in any realm of human activity).
I don’t think we need to go through the whole history of OSM-US except to point out that it is a good example of why you want to have the paper work in place before you bestow explicit or implicit special status on a partner organisation. Luckily that has been amicably resolved, but there’s still that other elephant in the room.
Imre went off on that tangent, and while there is a lot to be said about that, for example what a tremendously good idea it is to entice people that are already engaging in a extremely risky activity to do so in an organized fashion so that the OSMF can get some brownie points out of it, that was not what I was talking about.
I was just referring to the run of the mill every day stuff like people going AWOL for one reason or the other, corruption, fraud, embezzlement and all the other stuff that actually happens.
