to do that in your forum
Admin CP -> Styles & Templates -> Style Manager -> forumrules template
Find
Code:
</thead>
<tbody id="collapseobj_forumrules" style="$vbcollapse[collapseobj_forumrules]">
<tr>
and replace with
Code:
</thead>
<tbody id="collapseobj_forumrules" style="display:none;]">
<tr>
Enjoy it
