Alright guys, I am working on building a website for a campaign (I can't say which, but it doesn't matter) and I need to know a good service to manage our online contributions.
Do you know of any good online management sources to handle that kind of secure transaction? What do the big campaigns use? Where would you go to do something like that.
Over 100,000 people read this site every day, so I figure someone must know the scoop about how it works.
