Some info after I checked this out.
Its not MD5.
You can get user stats without logging in.
You could technically change these stats, but that isnt discussed on this forum and I am not sure of a proper way.
If you are an advanced SQL user/manager, you should know how to get around directly connecting to the server, while still using a proxy because the SELECT statement is already started for you somewhere *HINT HINT*
I dont play this game anymore so I dont see the point in trying to go further with this.
