I'd like to hear what you're using and why you like it. I have a hunch that we're going to be using more distributed version control than your average group, just checking. So...
Git? Bazaar? Subversion? TortiseSVN? Mercurial? CVS? Perforce? or "Revision control is for weak need mortals. I etch code directly on silicons wafers like the hacker god that I am!"
Talk amongst yourselves.
git
small, fast, in active development and cross platform. Fast to install, less documentation. Originally I used cvs with a p-server which worked nicely allowing me to distribute dev & other files across other machines. But was a begger to install. Then I tried svn but never really liked a) lack of clients, confusing setup documentation.
Using Git now as I wanted a SCM for a new project and it was the fastest to install & use. Git also has the advantage of doing the same as svn but with less keystrokes. [1] Can also be used individually as a tool as well as a group. [2]
Having said that svn, cvs, rcs are still usable just not optimal for me.
