I have some ideas to enhance dataphor website and increase contributions, usage and popularity:
Get an opensource JIRA license (it is free), that way it will be easier to report bugs and/or submit patches if we have fixed or enhanced something (http://www.atlassian.com/opensource/).
The wiki based site was a good idea, but it has been lately under attack from spammers, we need to prevent those attacks using CAPTCHAs.
I you downloaded the last setup file of dataphor, you know it has a really excelent pdf based documentation, I would like to volunteer for copy&pasting and wikifying it in to the wiki based dataphor site (currently down), that way it will be enchanced by the community and it will also act as a way to promote this project in the general developer community, I learned a lot about the advantages of Dataphor thanks to this PDF file, but whenever I want to share this knowledge with someone else I find I can not simply "share an url pointing the manual" the way I can do it with other opensource projects.
Do you have other proposals?
