EDIT: OK so there’s an even easier way to do this… Click on “Repository viewer” on the right hand menu under the “Development” heading

OK, so for some reason when I want to view Drupal modules I can’t access them via the usual “git clone (git_url_here)” command.
So instead the source code can be accessed by going to drupalcode.org … but how? Good question :D!
As an example, let’s say you want to check out my sandbox project https://drupal.org/sandbox/ajosephau/2105389 ?
Go to http://drupalcode.org/sandbox/ajosephau/2105389.git
So the format is http://drupalcode.org/sandbox/”USERNAME”/”GIT_REPO_ID”.git from the URL.
To download a particular version, click on the URL “snapshot” for a particular revision.
