A guy called Court has put together a video tutorial and article on using TDO Mini Forms, my free WordPress plugin.
The video is pretty good too as it shows you how to create a submission form and an edit form. I think I may be adding a link to this on the FAQ!
As a footnote to the video, the latest version 0.13.7 does include Custom Field editing and the compare view for edit posts is now working.
Also check out his site for indie musicians called indilean that uses TDO Mini Forms too.
