Used to be on a yard with someone who had BOB1 - no clues as to what his name was there! Good idea though, although can remember half thinking it was a bit like having a private reg plate.... lol
CVS - My initials - he doesn't have a long posh show name and couldn't think of anything better - just wanted it to be only 3 characters seems painful enough anyway!!!
Onyx will be getting NYX next month - I could have had his full name but think that O and 0 can be confusing, I am already plotting the 'private plate' for the one due this summer.
