A very very nice idea BlueSfear! Up until this point I mainly made use of bookmarks to form a list of sites that accepted tutorial listings... but now that you have this handy list, I think i'll use that instead.
You know the next stage don't you? To develop a universal submission form that will submit to all these websites as standard. My GOD that would be a timesaver. Hell, I'd even pay you for such a service to save my sanity!
