Thanks for the replies

Glad you all like the idea in principle.
Having read what you've all said so far perhaps weekends are not the best days to go for. I personally can not do weekdays during the day for the next 3 months as I have to work full time to cover a colleagues leave

but I know quite a few people do scrap during the day and this suits them better because their kids are at school. What about if I pick a time that is a week day evening in the UK which will make it afternoon in the US?
For instance
if I started a speedscrap at say 7pm GMT time it would be 2pm ET. How would this suit most people on a weekday?
