You've welcome!
I've delegated some RC to you which should be enough to interact.
If I remember correctly, the memo key is to send encrypted memos to other users.
The posting key is for posting (duh!) and the active key is for wallet transactions.
The master password is necessary if you want to generate new keys.
Thank you so much for the delegation. New keys you mean is it changing of the posting and active key.
Right. You only might want to do that when you think someone somehow had your private keys.
With the active key they can withdraw funds from your wallet.
Okay, thank you so much
