Timezones... Meh. Unfortunately a lot of my BBM buddies live in America. Mainly because I can call my UK friends for free, whereas UK --> USA, heck no.
So like it or lump it, sometimes I just end up with less sleep than I'd like.
If you could abolish timezones instead Tom, and make everyone live with GMT, that would be fab. You might have to go to work in the middle of the night, but you'll soon get used to it
