I'm back in the office this morning and trying to catch up on emails etc.,
If you've emailed me in the last week or so and haven't got a reply now you know why 🙂
Of course if your email didn't have a semantic subject line I probably won't find it ever - sorry!
I've also got a bit tired of clients being negatively affected by WordPress' dumb caching (or simple lack of it!) which has led to this.
All I'll say is this. When this site made it onto the frontpage of Digg the server barely flinched. If I'd been using a default install of WordPress the site would have taken out the entire server...
