Erm... If you don't know how to, my advice is don't do it. Looking at your active days awards, you're somewhat of a noob yourself. But in general explain the game and give them a few volleys, helpful tips etc. etc.
I've played less days then her and I know how to guide and help new players. I have done this with several. She may have been playing less time then you, but shes not exactly a noob. )
