Thanks for your feedbacks.
As I always said, the best contribution I may receive for this project is active contribution to the community: support, styles, knowledge sharing, and so on...
If I wanted to make money with this or similar project, I would never have started an open source project and community.
The money donations and banners revenues I received so far just cover part of the hosting costs (I'm on a managed dedicated server) and I'm quite happy for that, so thank you very much to all the donors and also to all the community members who made this possible.
Open source projects are not made by money (even if some of them have good contribution revenues now) but by good active contributors.
This is my idea, work with current IP host (whoever IP is hosting right now) for referral fee. IP can refer new users or switch host. It will help something.
I'm already in touch with another hosting for something similar...
