conditional for "who is online"

[moonclamp]

I've created a usergroup for people who's contact info I want hidden (email form, messenger details etc) regardless of what they have entered before.

I've got <if condition="$bbuserinfo[usergroupid] == 15"><else /> for the templates that they might see

I've got <if condition="$userinfo[usergroupid] == 15"><else /> for the memberinfo template

I've got <if condition="$post[usergroupid] == 15"><else /> for the postbit template

However I can't find anything that works for the who's online page

<if condition="$vboptions[usergroupid] == 15"></else> doesn't seem to do anything, neither do any of the above.

Any suggestions?
