I am working on a roadmap for the site. It will be a basic one page overview of what features we will support and when. Until I get it done here are some of the top requests:
-Better email integration
-Chat and other real time collaboration
-Manage contacts and those interested in the project
-Make it easier to link/embed images and other media
-Expertise management
-Rich visualizations and mash-ups of local and distributed data
More to come....
