You guys are doing this on your own volition as there is no official organization for BTC?
There's a handful of people (3 or 4 I think) that have merging rights to add or remove from Bitcoin's code. Then there's dozens of contributors who offer changes. The 3-4 that push the merge button only do so when they get the agreement of at least another 3 or 4 code contributors who are regulars on the project. If it's something totally trivial, like changing documentation, the mergers might not bother wasting time getting agreement first, though.
It's pretty informal overall (and typical for an open source project in that regard).
