it is not clear what you are actually asking to happen - the GNU license permits you to make any modifications that you desire - you do not need to ask permission to put our logo on the program and you do not need to give anything for the service - the service itself is also open-source and you can host your own instance of it without using the service hosted by savioufairelinux - as a developer, you must also know that re-branding is usually a trivial task that is deferred to downstream developers - so its not clear why any formal partnership would be necessary or what it would entail
