In order to receive notifications through Skype instant messaging your must first add My Wallet to your contacts list. Our Skype username is "blockchain"
You may receive notifications for double spends, transactions without the minimum fee requirements or non-standard scripts. It is therefore highly recommended you do not use these notifications to process payments without an additional source of verification.
My Wallet normally only stores an encrypted JSON payload of your wallet and hence is not aware of your public keys. Enabling payment notifications will cause your public keys to be inserted in a separate table along with your wallet identifier. Enabling notifications therefore sacrifices some anonymity however you can easily use a throwaway email address.
