Account help please--

Hi guys----is it possible to create a completely new account ( ie starting at zero profit/loss/ history etc), and a new nickname ? (God knows why I came up with the present one ---hateful !)--------i haven't had a bet for about 3 years, but used to be a four figure per bet punter in my heyday ---ie. up 5k mon /tues, down 5k wed /thurs etc etc--LOL----but  my account eventually ended up looking a bit grizzly after a few mad bets, and bad results in a row (I think that putting the £10k I had won on Authorised in the Derby, onto him in the Sandown race where Ryan Moore came un-noticed under the stand rail to beat him, was the final nail in my nervous system)------and although I now fancy a small flutter on the NH season ahead @ about £50 a go, I can't face seeing that bladdy profit /loss account screen from the days of my "madness"-------any help appreciated. -----Alternatively, perhaps you would all advise me to keep well away from the demon that's calling me !!--thanks in advance--David
(going out shortly, so won't be able to respond till later today)
