Help with Forum Blocks

[kh99]

First copy the template block_html to another name, and edit your forum block and enter your new template name as "Template to Use" (at the bottom). Set the "Cache Time" to 0.

If you want the block to disappear completely, then add <vb:if condition="$bbuserinfo[userid] != 0">...</vb:if> around the existing code of your new template. If instead you want to show something else to guests, I think you could replace {vb:raw content} with

<vb:if condition="$bbuserinfo[userid] != 0">
{vb:raw content}
<vb:else />
