I'll give you an example. Look at this:
Code:
<if condition="...">
Do something
</if>
</if>
See how there's an extra end if? If you do the template edits required for my modification, you get:
Code:
<if condition="$memid == 1">
<if condition="...">
Do something
</if>
</if>
Everyone will see this.
<else />
No one sees this because the above end if cancels out this condition.
</if>
