Hmm. Well, now with this:

<!-- BEGIN MODIFICATION -->

<vb:comment>
<vb:if condition="$show['avatar']">
</vb:comment>

<vb:if condition="$bbuserinfo[userid] == 1816 OR $show['avatar']">

<!-- END MODIFICATION -->

Trying to save I get:

The following error occurred when attempting to evaluate this template:
Invalid Tag Nesting
This is likely caused by a malformed conditional statement. It is highly recommended that you fix this error before continuing, but you may continue as-is if you wish.

I've used the <!-- --> tags in the templates before.
