Once again, I must apologise most profusely for the unexpected downtime; something happened to the server, I've no idea what, but it's fixed (or been fixed by someone more knowledgeable than me) now & hopefully won't happen again.
In the meantime, please make a note of this e-mail address: javickers@yahoo.co.uk - if you discover the site is down, please e-mail me on that address and I'll look into it asap.
