IMPORTANT NOTICE
Today I got reports about unauthorized address change requests received by some deepbit users. Maybe this is a consequence of Bitcointalk forum security breach or just a coincidence, but I recommend checking your mailbox and ensuring that everything is still fine with your account.
Permanent bitcoin address locking is seriously recommended, but be sure to backup your private keys for that address and double check if it's correct since this operation cannot be undone.
This issue was reported by ~5 users, but this still may be a concern, so payments will be paused for a few hours so everyone can check their addresses.
