How to add a search form on a non-vb page?

[Lynne]

If you created the page using one of the articles in the Articles forum, then the $head and $headinclude are called and the value for that should get filled in automatically in this line:
<input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />

It will say "guest" if the person isn't logged in, and it will have the value in there if they are.
