[MENTION=6686908]As for a retroclone of 4E that is like OSRIC, rebuilding the edition as far as legally possible under OGL, I've tried to start a project called 4SRD but it currently suffers from the problem that I have zero free time to spare. Help is welcome.
I like the open design aspect of this, and I would like to make some contributions. It will be a nice resource when the official on-line resources for the Fourth Edition fall away. The wiki format is easy to hyperlink for ease of use. Wikipedia itself has several how-to pages to instruct people how to format pages and link pages.
