I've used SourceSafe both for my own applications at home, for remote clients and at very large shops (IBM, Peachtree, Equifax, etc.). It works extremely well. Don't be fooled into buying something like PVCS thinking that it must better because it's more expensive. The only thing PVCS does better than SourceSafe is branching, which is not something most people have to do. Regarding multiple concurrent developers, the only thing to be wary of are things like resource files and such that do not merge well (simply due to how the resources are automatically numbered by Visual Studio). At various shops we simply defined the rule that this file could not be checked out by more than one person at a time. If you do run into problems with your resource file in this environment, you can always use Anna's great resource id editor[^] that will automatically go through and fix the numbers for you. Cheers, Tom Archer, Inside C# Mainstream is just a word for the way things always have been -- just a middle-of-the-road, tow-the-line thing; a front for the Man serving up the same warmed-over slop he did yesterday and expecting you to say, "Thank you sir, may I have another?"
