WARNING: If you input your passwords it will be as "cleartext" in the file. Meaning that anyone with access to that file can just see your passwords. Up to you to decide if that's safe enough for you or not.
NOTE: If you have Skype installed in a different directory, then change it accordingly.
NOTE: You can leave the password field empty.
NOTE: It's best to log off from Skype before doing this, otherwise you'll end up with a lot of skype windows.
