i suppose i registered an account on mining.bitcoin.cz during the period where slush hadn't intended for registration to be open. in any case, i left my computer running over night, and when i went to check it this afternooni noticed that i was having trouble connecting and my threshold was set to the amount you had for blocked accounts.
i guess i'll have to wait until i get unblocked. in the meantime can anybody recommend a pool that function's as well as slush's does? thanks guys!
