You can contact me via email to andy at andylangton.co.uk. I use fairly strict spam filtering, so if you want to sell me pills or enlarge certain parts of my body, I'm unlikely to see your message ;)

If you're after general web development or marketing advice, I recommend the Webmasterworld forum, where I'm a moderator and (fairly) frequent contributor. You can also use Linkedin's connection feature.
