I see that your forums are still on UBB.threads 7.5.3

In the "Edit Preferences" menu for your user profile, Set "Total topics to to show per page" to 99, to do 99 at a time.

...

Or edit /scripts/changedisplay.inc to increase the maximum limit from 99 to "500"

FIND THIS: "$PostsPer > 99"
REPLACE WITH: "$PostsPer > 500"

Then set your user profile "Total topics to to show per page" to 500, to do 500 at a time smile

When you're done, revert the script back to 99, and in your user profile.
