Hi, I was exactly the same as you, I didn't have a clue.
It was really easy, I used blogger from google, you learn as your going along really.
I loved doing mine, I'm going back to work next week so I've brought it to a natural conclusion as Tabs is now one, but I was reading through it the other night and it is a really lovely record for her to see how she did or how we did together!
Enjoy it, but I must warn....it is addictive!!!
