Exchange portable telephone numbers (handy?), take a laptop or tablet with you and log on to Chrons, plan in advance which conferences you intend to visit - you'll still miss people. But you'll find some of them - and those might already have contacted others. While some people might be there without having said in advance.I just wonder how people can find each other at such a big event ...
Yes, an official Chrons hat would be handy, but with all the many and varied costumes, would it even get noticed?
