Dress Code: Please wear clothing…
Nice little throwaway line in the documentation to see if anyone actually reads it. For anyone going to SMX-London, please note that I do intend to hono(u)r that clause and will indeed be wearing clothing.

Glad to hear you’ll be wearing clothes… in London… in the middle of November!! I’ll be sitting on the beach. I may have to put on a sweatshirt. We’ll see.

Would be kinda hard to focus on the topic if your sitting next to someone your attracted to ;p . Clothes sound like a good decision
