And what do you need to do to be in with a chance? Simply leave a comment on her post and she'll draw a winner at random.
That's it. Simple as that. Who said that you can't have something for nothing? I'd enter it myself, only I might be accused of nepotism, bias and preferential treatment if I happened to win!
Now don't ever say I'm not good to you .... go on then... go forth and win something. :D
