One problem I has was when I used polyvore to make my moodboard and I realised I had done it wrong by creating a template instead of a set so I had to start again. As I clicked 'save', once I'd finished recreating my moodboard, the page refreshed itself and deleted all the work I did and it's draft. Luckily the one I had made previously as a template was saved, so I took a screenshot and cropped it in photoshop to upload to my blog.
