I have been messing about with the final section of the witches for ages. Unfortunately I'm having trouble getting the information I need as I don't have all the pieces I am writing about. It is nearly there though and should be ready in the next few days.
In the meantime I have been playing with the the Ankh-Morpork app!! I initially didn't really understand what it was. I knew it was a map but I thought to myself, well! I've got a map upstairs so I didn't bother looking into it. The other night my other half downloaded it for me and it is incredible!! It is so detailed and there is loads to see. It is made even better with achievements based on you having a good look round. I can highly recommend it. It is expensive for an app but I have had a good couple of hours entertainment so far and I'm not close to doing it all yet.
