How can I change settings for all forum members to force them to see all the threads?

How can I change settings for all forum members to force them to see all the threads? It was a wrong setting in the beginning and now some of forum members can't see all threads. Most of them doesn't know about these:

Showing threads X to Y of Y
Sorted By: Last Post Time
Sort Order: Descending
From The: Beginning

I want to run SQL-query and change it to this (From The: Beginning) for all forum members by default. After that advanced users can set their own. __DEFINE_LIKE_SHARE__
