Yes, Source Safe is a tool that gives you the ability to have multiple
people working on the same project. This is accomplished by allowing each of
the developers to have a local copy of the whole project in their own
machines, in other words, it would be like if you were the only developer
working on the project locally in your computer.
Since multiple developers make changes to the files, source safe keeps track
of all these changes for you. So one developer can "Check Out" a certain
file form source safe and modify it, once the modifications are completed,
the developer would "Check In" the file so that other developers can "Get
Latest Version" of the file so that everybody's computer has the newest
code.
Like Rechard Blewtt told you, instead of working from a server you will have
to make some modification so that you host IIS in your local computer. Also,
like Jon Skeet told you, don't be so quick to say what on your mind, I know
these things can be frustrating and some time we say thing we did not mean
to so I have no problem letting this one go.
Source safe is nice but you still have to do some research to figure out how
the software works, further more, Microsoft source safe des not work
seamlessly with .Net, there are some things that may annoy you. (Like if you
ever need to rename a file).
You don't have to use Microsoft Source Safe, there are other source controls
tools other that will allow you to do essentially the same thing.
