Is there a way i can see my rejected percentage on the website, witout scrolling until i find my address?
A Search function?
On GUIminer-script, I can't see the difference between stale and rejected?
And the Stale shares pays out, correct?
Sorry for all the noob questions!

Stales pay out when they are from a prior coin.
there is a search function where you can type in you adress.
I really dont know, I use cgminer, once you get the grip of the command line style things are simple.
