Very excited. I have been checking to see if the next (4) Block was available for download. Actually according to the website if you click on Block link it only shows the first 3. By chance I was looking at the best seller section and I saw it there!!!
So anyone like me who has been waiting for it, and not realised it was available-good news!!

OK I was going to have an reasonable early night (for me anyway), but I guess that won't be happening.... time for a quick bath while waiting for the download.....oh the excitement!!!
