I am confused on whether to install the CollabNet Subversion Server and Client v1.6.9 (for Windows) or the Subversion software download at Tigris.org? Both are suppose to be free open software? And there is CollabNet AnkhSVN which also suppose to be free ? and works with Visual Studio which we use for our dot projects athough we need to manage non dot net projects and documents as well? So which ones do you download and use to make a free cfm system to manage dot net projects and non-dot net projects and documents?
