If I've had a 1on1 through Mastermind am I eligible for the lounge?

Hey,

Someone mentioned for me to ask,

If I've had a 1on1 with Keychain in London, through Mastermind, am I eligible for the lounge?

I have an active journal if that makes a difference: http://www.theattractionforums.com/f...e-welcome.html

I'm registered with billthoven@gmail.com under the name William Charles Brown

Thought it'd be worth asking!

Thanks
