Hello ladies,
first of all it takes a lot more to stop me from contributing to the Joomla! project.
In the dark ages - before GitHub - it was a lot more complicated to even offer a contribution. I fell very comfort now with the possibilities that git and GitHub pull requests offer and if a pull request (ore more) are not accepted - that's fine with me if there is at least some response.
But yes, there is still some room for improvement in the communication between the contributors and the committers.
As for the XML exporters..
I wrote that part for a project and thought that it could be useful for the "rest of the world" - if it is not the case, just let it go.
If somebody wants to update and resubmit the pull request - excellent :)
Please stay calm - the Joomla! community needs both of you ;)
