Typical problem, you have just gained your full project permissions role in Drupal.org, and you make your first mess... you have promoted your so loved first project without changing the Short project name.

Well, you have a problem, but not too big. Drupal.org will not allow you to rename your Short project name, so you will have to create a new one if you don't want to have an ugly url like that: https://drupal.org/project/2062343

Fortunately git can help. You will simply have to:

• Create a new project, sandbox or not,
• Go to the "Version control tab" and get the url of your new git project, something like: programadoresweb@git.drupal.org:project/2062343.git
• Go to the folder of your old sandbox, the project in which you cannot change the Short name, and change the remote for this folder. For my url example, the command will be: git remote set-url origin programadoresweb@git.drupal.org:project/2062343.git
• Nearly finished. You probably have to merge, as you will have to make your first commit in the new project: git pull
• And finally, git push origin master will get the job done.
• Remember to create a new branch, like 6.x-1.x and commit to that one to create a new official, downlodable release of your module. Congratulations :-).

Next time, take it easy cowboy ;-).
