If you have already got a theme(s) listed as a full project on Drupal.org then you will be aware of the process of having to have your first project 'reviewed and tested by the community' before being granted access to create new full projects.
The people who review and devote time need a big thanks as they enable to D.O. community and resources to grow, so thanks!
This process however, is time consuming and left to the 'few' from what I can understand, which means the process takes a long time. This can be frustrating for potential contributers and could put off some potentially great contributions from ever being submitted.
With this in mind, I have been through each of the submissions to sift for themes and a list of the current ones waiting are below. There aren't as many as I expected, but it would be great if some establish/seasoned themers could pick an issue and try and help.

I personally have a theme in the list, but that's not the main motivation for this post (a small one but not main).
