Things may have changed since then, though.
Good luck! :)
In the future, it would be good if we could keep openacs.org much closer to a stock install, and get better at bringing enhancements from openacs.org back into the code base.
I'm starting to nurture an idea of having a fixed 3-month release cycle, so we'd have a new release every quarter, and then simply cut scope for each release in order to make the schedule a reality. That would make it much more feasible for everybody to keep in sync, because they would have to wait at most 3 months for a new feature to come out as part of an official release.
We'll try to gain some experiences during the 5.0.0 release cycle, then we should have a discussion and a TIP about the release process going forward. Just loose thoughts so far.
