Jeri... re clicking the "d" for the last fifty posts. I just timed the load times for three threads :

14 post thread - 4 seconds.
clicked "d" on a 130 post thread - twenty seconds
clicked "d" on the MOAB - two minutes, one second

Try it for yourself. The MOAB is a pig and should be considered for closure, if it would lighten the load.

HEY - I said "considered" and "if". Don't all youse git yer knickers in a twist.
