I'm going to sign up... and think it would be fun to do it with a couple of others at the same time? So if anyone else fancies it, do sign up and lets compare notes as we go.
I followed PollyRoulstons advice and did a quick search - lots of Mumsnetters seem to have done it, its clearly good quality and not too expensive ... but yes VERY enthusiastic and slightly cheesy presenters. I can live with that and find it rather endearing at the moment! Going to paste Polly's summary below as I found it very useful and succinct!
