Is it my imagination or has the forum been running a bit choppy lately? I've been getting a lot of those "can't display page" errors :(
Must be your imagination, I haven't had a 'can't display page'-error in months/years.
I've never seen that myself, though you might be getting a time-out problem if the site goes through a lot of servers to get to your computer.
It's gone now... must have been one of those 24-minutes thing ;D
I only mentioned it because all other sites seemed to be working fine.
