Commits don't appear; can't create releases

While this issue fixed, I create development tarballs by hand and add to the project page like 'official' release table.

"can you change your name in git..."
If i remember well, i try this before, but 'non-fast-forward' pushs prohibited on Drupal git repos, so IMHO it is impossible...

I try this (of course in the `rename.sh` i change the name and email addres):

As I think, "delete your commits from git" is the same question, but if you know how can i make, please ...
