Here is the website if you are interested in custom stats:
http://www.qw-sigs.com/All you have to do is search the name of the player you are interested, i.e. their online account name.
This will display all kind of stats that isn't visible on the community etqw stat page, e.g. head shot ratio etc.
You can also create your own etqw signature.
However, you should note that sometimes the database goes offline. They have server issues everynow and then. So don't panic if it can't find your name, it could be just a connection issue.
