If you go to the "adresses" tab you will be able to right click and press "public key" to get your public key.
Wether or not it's 'safe' to give out your MPK depends on your definition of 'safe'. The holder of your MPK won't be able to spend your coins, it can however see all transactions that you have made and will make in the future.
No, it will not let me add the Master Public Key.......I need to find a way to export the Public Key for my Electrum Wallet Bitcoin Address.
I do not have an option to get my Public Key when I right click the Addresses Tab, it only allows me to access the Private Key with my Password.....I don't need my Private Key though.
