Hey, I'm thinking of building a web app for signature campaigns. I see that it's very much a hassle to keep track of which campaign is currently running or has ended. I also want to allow participants to submit their links where they have posted, so the person running the campaign (manager) can approve or reject the post links. Do you guys think I should build something like this? Would anyone use it? Can you guys mention any campaign managers? If you like this, what kind of features would you like me to add?
