What is the proper response to my partner's initial two no trump, when I am trying to show my Diamond long suit, without asking for Heart transfer. Also is there stay man ( three clubs) response proper to two no trump, if yes, when and how??

I have played for a very long time on BBO, and used claims many many times. Finally it occured to me that I never conceded and actually do not know how to click or write concede! Can anyone help please.
