Thank you so very much, that’s generous of you! Now it’s working! =D
To clarify how to do it to anyone with the same problem: I set the reward recipient like shown in the first screenshot. I must have set both text boxes to my own address the first time around before I knew it would cost 1 coin. Don’t do that, people. Make sure you have your own address in the top text box and the pool’s address in the bottom text box of the set reward recipient form.
It says clearly “Your account” and “Pool account”, so I don’t know how I manged to fuck it up the first time around, uh well…
It’s working now guys; it’s working! How about that? =)
