Hola Marcos,
There is no "official team" at the moment. However, you are welcome
(in fact, MORE than welcome) to start contributing patches. Take a
look at the repository and clone it with git:
http://github.com/myabc/nbgit/tree/master
Send patches to this mailing list or send me a fork request on GitHub.
Take a look at the issue tracker
(
http://code.google.com/p/nbgit/issues/list) for an idea of the areas
that need attention.
If you're able to help out with a couple good patches, then I have no
problem giving you commit access to my repository.
As an aside, I realise that NbGit is not getting the attention it
deserves. I'm pretty much open to handing over the project to anyone
who's able to take the lead on it.
Alex
