Quick announcement today: the 36x24" interior routing protocol posters are on sale this week for $9.99 plus shipping. They make great lab decor!
If you don't have one (can't imagine why you wouldn't); pick one up! $10 is too good to pass up.
Hmm, I only see a $26 shipping option to UK :(
@mellowd: Yeah, sorry about that. I've not yet found a way to ship internationally at a decent price. For readers outside North America, it might be more economical to take the (free) PDF to a local print shop and have them create one (or several) for you.
