SH, I think your statement "For the sake of us keen golfers" was badly put.
I'm a keen golfer, I hold a club h/c of 13 , I also have a today golfer h/c of 11, which is based on the Congu handicapping system, I use todaygolfer for all my rounds be they club comps or friendly games in the uk or abroad.
Just because someone does not either want to join a club or maybe does not play enough to warrant joining one, why should they not be allowed to enter cards on sites like this and have an idea of their H/c, odds are they may just post good scores in which case they will be playing off a better h/c then they are really capable of, or they may post bad scores in the hope of getting a higher h/c, both cases they are cheating their selves.
But if they are keen golfers like the rest of us, I'm sure they would want a true idea of their standard so post all scores.
This site is for keen golfers to meet up for friendly games, If they want to use a club h/c,this sites h/c, todaysgolfer, virtual golf society, golf magic or any other sites h/c thats fine with me.
