Because you probably asked a question that is already in the FAQ. That's what a FAQ is for: so I don't have to waste my time answering the same Frequently Asked Questions over and over again. You must be new here. Welcome to the Internet... n00b.
E-mail me and bear in mind that this is something I do in my spare time. If I'm short on spare time I might take several days to get back to you. If you have questions about one of the club nights or an upcoming event you'll be better off posting in the forum or contacting the promoters of the event directly.
Today I sent out a very rare mass-mailing ostensibly to announce some upcoming major changes to the site, but also to do a user "ping" to weed out inactive accounts.
