Hey,
After giving the logo, project owner can do whatever she wants with it. I'm not expecting anything from them. They can credit the project with courtesy though.
An interesting scenario would if I use one of your logos for my project. Is that logo still available to be used by others? Potentially, more than one project could be using the same logo.
One logo can be only given to one project. This project will have all exclusive rights of the logo.
Every logo has one github issue that you can introduce your project to and claim.
Community can upvote your comment and you can upvote other projects as well under these issues.
