If you're not going to use them, turn the mining off and leave more for those of us that will use them

SECONDED IN THE UTMOST ALLOWABLE MANNER
/thanks
It appears that neither of you understand how merged mining works.
Each valid Bitcoin share has the potential to also be a valid Namecoin share, and only needs to be compared against the Namecoin chain - there is no extra mining or such going on.
Although, if he deletes his Namecoin address, his reward will be split among the rest of the users, so that could work I suppose
