This is a Tcl-based application, similar to Wikit, but offering more advanced features (support for multiple groups, project areas within groups, forum-style posting, attachments, images, version history, page locking, multiple authentication schemes, activity tracking, branding support, and more). From the web page:
"ProjectForum provides a powerful but easy-to-use solution for flexible workgroup collaboration and coordination of projects over the web."
"Use it for project planning, todo lists, design notes, task assignments, meeting notes, problem reports, team discussions, collecting feedback, research, brainstorming and more. "
ProjectForum is a commercial application, but a free version is available. It uses the same underlying technology as CourseForum.
See http://www.projectforum.com/ for all the details.
This product is currently at version 4.1 .
Hosted ProjectForum areas are being offered free to qualifying Tcl/Tk open source projects! See http://tcl.projectforum.com
