Aargh, the website is intermittently down too! I've worked out that it's the people who I bought
www.llamaserver.net off who are screwing up, which is why both the website is going wrong and some e-mails not arriving. I guess they're having problems and there's no-one to fix them because of the bank holiday weekend (um, that's a public holiday, don't know if you have bank holidays elsewhere).
So sorry guys, it seems to be a cursed weekend. I'll make sure order is swiftly restored when I get back (Monday night/Tuesday morning).
