A slight update...
Just spent a bit of time updating www.oneroundpebble.com today. Now the navigation bar on the left should be a lot quicker to load, as it now dynamically loads the child nodes. Hopefully it also works on more people's computers.
Had to fight a bit with various asp.net 2.0 configuration bits to get it all working properly, and various other fun stuff, but it all seems to work now.
If anythings broken, let me know!
