You are very brave, but as has already been written, competition is very strong. There are forums that pay for posting! I'm not sure if you are ready to fight with such competition.. Anyway creation of this site is for you a good lesson and experience!
Good luck with your projects!
Indeed, but not all forum that pays for posting get many active members. So I think it depends on how the forum attract people to come, as I know this forum (bitcointalk) had many members in the past not because there were many signature campaigns but because its contents.
