Fedora Logo Policy

The Fedora logo is now final and available for use by the general public.

The interim process for getting permission to use the logo is as follows:

1. Send an email to logo at fedoraproject dot org with the following: a. Your name and email address. a. What country you're in -- i.e. the legal jurisdiction. a. What you're doing with it -- no more than a paragraph. 1. If you're doing something odd with it, we'll ask more questions. 1. Once we agree to your use, we will send a basic "license agreement" in email, that will say something like "don't use our logo for bad things." If you agree, return the email saying "yes, I agree". 1. We will send you the source files for your use.

That's the interim process. The real process will be available within the next few months.
