I will strongly advise that you message Royse777, to allow you upto 14days to remove sinbad signature and avatar. You have to wear your project's avatar and signature and also launch a free campaign such that people that are not paid currently for signature will help promote your project.
After 14 days you may decide to return to sinbad promotion while leaving the campaign open.
As long as this project is aimed on forum users only there is no need in additional signature campaign. Majority of users who need image hosting is already aware of this project, there are translations to main languages, there are advice of using it when there are questions. Signature will hardly give much more. If there is a wish of helping the one can add this project to a signature and this will be good, but there's no need to do so mandatory.
