If you have mined within the last few months, these actions won't affect you. If you haven't mined recently, I'm going to ask Chris to force payouts to the addresses on file so that the balances of all old accounts are zero. We'll also be updating our documentation to warn customers that if they stop mining for a very long time, they may have their remaining balance paid out even if they did not request a payout. The lines added to the documentation will state:
Accounts which have not seen any mining activity for 90 days will have full balances for all coins paid out to the payout addresses on file, minus any transaction fees. If the balances are less than the minimum network transaction size, then balances will not be paid. If there is no payout address on file, then Prohashing retains no liability for balances in accounts with no activity for 90 days that do not have payout addresses entered, or which have invalid payout addresses entered. To make sure that you are fully paid even in the case you leave the pool, make sure a valid payout address is always entered for all coins.
