I like the idea of a "projects forum" were people can change ideas and experiences. To use such forum as a development forum for projects may be harder since it could be hard to easy cover all (if any?) ongoing projects.
I've been thinking, what about some kind of projects forum where people can share their ongoing projects, such as helpful programs, start new projects on their own, and even work on things for AO and promote community mentoring in learning and trying out new things, as well as displaying current skills.
If possible would this be a nice idea for ongoing projects :).
So, if we're about to develop a project, we can always join freshmeat or sourceforge, sign up the project either as AO representative.
