I left unsigned positive rep when I started since I didn't realise it was an anonymous system and assumed the sender would be identified - and sometimes I am just ham-fisted and hit the wrong key. But thereis a world of difference between anonymous positive rep and anonymous neg rep ( unless you are stalking someone of course!!!). It is the difference between the door bell ringing and opening the door to find noone and opening hte door to find a bunch of flowers on the step
