Has anyone used a free content management system that they like that has a nice GUI front end? I have used CVS, SVN with tortoise but I am looking for something that would be more user friendly for a wide variety of people and documents. I have used Surround SCM from Seapine, and really liked it since it was easy to show people how to use it, but it costs too much for a small company. I see there are a few projects like this for SVN (RapidSVN) on the wiki page, but does anyone have experience with them and can offer insights? Basically, I want to keep source control for our software. But also want a common interface for all company files. I definitely don't want/need a Clear Case/Quest solution that can peek into files and create all sorts of crazy traceability matrices, I really just want something dumb that stores versions of documents in a repository. But one that is not accessible through explorer. All machines are Windows based. Thanks for any insights!
