Well the good news is that his page is now 100% valid....
The bad news is that somehow i lost most of my recent entries on this page.
Oops.
Oh well they are all still in the individual entries and the archive but i dunno what happened exactly so i do not know what to fix.
It is probably because you have it configured to only show entries from the last 10 days.
If you want to change it, log into your MT account and go to weblog config. it is somewhere in there.
Hope that helps.
