Hi,

You are running in dynamic mode so like Adrian says "run nph-build.cgi --flags" to update the new flags for your links.

This operation re-checks the date links were added against the current date and re-flags them either as new, or not, depending on the date.

If you don't do this, nothing will change!

If you don't have shell access, try using Build > Build Staggered - then stopping it after it's updated the new and cool flags.

Hope this helps

Cheers,
Shaun
