Hi Biggles, not sure what happened to your account likely deleted in error.
And I agree the forum takes a while to get the knack of. The problem is it needs to be SPAM proof (ish). If it did not have the security features at login we would have hundreds of fake entries every day. As it is I spend half an hour a day trying to remove Russian SPAMers, fake entries with links to porn etc.
Your username may have inadvertently been deleted in this process. Please do set up a new account and if you have any problems just let me know.
