It has saved me hours of time since we started using it, code merges are now effortless. We've only been using Code Co-op for 2 months and already we couldn't live without it. Mostly vertical CAD application. For the last 3 years my partner and I literally worked out of my basement and we used SourceSafe on a server. When the server went down, development ground to a halt.
Integrations use to be a big part and big hassle of the day.
Now it's a joy to integrate. We are so much more efficient now. Code Co-op has already enhanced my approach to developing software. I am using it now to manage an MS Access 97 project and I will be adding more projects as time goes by. I also have a huge investment in our order processing system written in an old long-dead DOS language.
