Confused!

As I sit here, patiently waiting for D. Penns to accept my friend request on facebook, I can't help but wonder how the hell this site works! So far i've figured out how to write stuff and post pictures. Not exactly a blog master.

Needless to say, it would be very much appreciated if someone could help me out. I'd like to customise my page a little more successfully. Comments would be useful, please and thankyou!
