We have started a new wiki as a repository for all OpenClinica
documentation. It will eventually be integrated with Mantis, our
bugtracker, and the OpenClinica developers mailing list. For now though
you'll have to subscribe if you wish to modify the wiki.
The Wiki can be found at http://www.openclinica.org/dokuwiki/doku.php
Since this is very new it is sparsely populated. Feel free to request an
account if you'd like to contribute.
