I'm not sure if this is standard practice but I deleted my Dozy account in March 2012. It was probably the wrong thing to do and in late November I emailed Eric at customer service and asked if it could be reinstated. He was good enough to do that.
As it happened there was a technical problem and I was unable to get any activity notifications, nor could anybody see when I had commented on their answers so, in January, I opened a Dodgy account and left Dozy inactive.
I want some of the anecdotes from Dozy for a new novel and have been slowly downloading them. but no longer use the account for Q&A.
