What is wrong with your e-mailing the package owner if you fix a problem? You're suggesting that package owners take the time to routinely scan a second repository just in case someone might've fixed a bug for them. What a waste of time! You're suggesting that other people spend more time monitoring possible fixes you might make rather than have you take the time to write a simple e-mail message.
I've said it before and I'll say it again: COMMUNICATION is the key to making a project like this succeed.
If you're making local bug fixes and not informing one of your fellow OpenACS 4 porters, then you're not communicating.
It's MUCH more efficient for YOU to e-mail a package maintainer in a case like this rather than expect everyone else to be checking a second repository for bug fixes, figuring out how to merge them with their own work (which undoubtably will have progressed in the interim since they weren't informed that there'd been a bug fix) etc etc etc.
Domingo ... with all due respect I get the impression you want freedom to work on the project without accepting the responsibility of communication. For instance, you still haven't e-mailed me as to whether or not you're interested in finishing porting some of the packages you started on a couple of weeks ago. I've asked you a couple of times. Check the status page, there are several slots there with "DomingoA?" because I don't know if you're actually planning to work on these or not.
You need to COMMUNICATE. It's not about beaurocracy, it's about working together as a team.
