Counter Strike 1.6 HELP ME PLEASE?

I’ve got problems adding servers to my favorites.
If anyone can help me that would be great.
I would add more, but I don’t know if it will help.
Answer #1
Are you using Steam?
Answer #2
No.
Should I be?
Answer #3
Up to you, the Steam server list is useful, you can view it without launching CS, and if you enter a server, CS will start up and take you straight to the server.
Answer #4
Are you using a pirated version of Counter Strike? Because it wont add an official if you are.
