Peter and I are using WinCVS to manage a software project we are working on. Very nice system. If all goes to plan we will be able to work on different parts of the application together. Well worth taking a look at :

You have to log in to use the system, since it authenticates you to the server. To log in you must give your password in clear text. It is displayed in the dialogue box in clear text. It is stored in clear text. When you have CVS running the login window displays the password for all to see. I'm not that worried, I have a bunch of passwords which I use, so at least it doesn't compromise anything else. But it does show rather poor design.
Anyhoo, the program works fine, which is nice.
