thank you for your answers. To be a co-worker for another amiga-game-related web project is also an option, but i donīt see any options for this.
You are right, i should know what i can offer before i start to build up the project.
Its just the simple demand-offer-game.
I donīt want to create a rip-off of known projects, iīm fair enough to see that i donīt want any rivalry. So i need to find a niche for my project. I think i have some fresh ideas to add to the community, so we will see.
