There is no need to create a plugin to show the number of invisible users online.

Edit the FORUMHOME template and add Invisible: $numberinvisible anywhere you like.

The only weird thing about this is that I made the main admin invisible but it stayed at zero. I logged in with my other username which is in the "Registered Users" group and set him to invisible and it worked.


Edit:

<phpcode><![CDATA[ 
if ($totalonline (<phrase 1="$numberregistered" 2="$numberguest">$vbphrase[x_members_and_y_guests]</phrase>)) 
{
Invisible: $numberinvisible;
}
]]>
</phpcode>

I don't know how your code will function but I can tell you that you need to put text that you want to output into a variable.
So change this Invisible: $numberinvisible; to $myvar = Invisible: . " $numberinvisible;
In the appropriate template just add the variable $myvar in it and it'll output the text assigned to it.
