Collabtive is an online project management system that allows users to get together and access common information to complete group projects, even if they aren’t in the same area. The system has been around since 2007, and is used by tens of thousands of people to complete all sorts of different projects. This is an open source system, which makes it easier to get into the back end and make any programming changes that are needed as well.
There is a lot to like about this system, but unfortunately, the developers are not putting out updates anymore. The last major release was in 2009, and at that point they were still working on creating an effective plugin system. While their website is still up, and their system can still be used, it is not likely that it will be updated again anytime soon, which is a big concern.
