AARGHH!!

I was trying to post the very cool little link to a random selection of books from my Library Thing. It was and is not clear to me how to do so. This is the point at which I begin to hate and despise new technology! to rail at my lack of understanding of it and why it isn't explained in terms I can understand!! So somehow my avatar picture, my profiele, and my previous post links have disappeared and it says' books', but what i expected to be there isn't there. it may have something to do with me using a mac, I honestly don't know. But the worst thing is I don't know where to go for help! I need a human!!!!
