I joined a freelance editing/proofreading forum last year, paid $99 for the privilege of taking editing tests and bidding on projects. I never even got a nibble. The site did not have an open-forum type of access, though. All projects were offered through the site's owners, and there weren't very many projects to bid on.
Has anyone here had success on these bidding sites? It seems like there are a lot of people willing to undercut you for a dollar or two just to get a job. Am I jaded, or what?
