MaxUsersOnline and a Datastore Question

[komodo]

Hi, could someone please point me in the correct direction for understanding the implementation of datastores a bit more? (search didn't turn up anything for me) I run a BMW community (http://www.unitedbimmer.com) and do a lot of heavy customizations to the forum, however I never really did understand how the datastore variables are setup and read.

I have a new seperate page I created in the forums directory, referencing similar includes and forum functionality, and while arrays like $vbulletin->userinfo are populated, the $vbulletin->maxloggedin['maxonline'] variable is always reporting blank.

I've noticed most pages list that variable in the specialtemplates array, such as on the index.php page:

$specialtemplates = array(
        'userstats',
        'birthdaycache',
        'maxloggedin',
        'iconcache',
        'eventcache',
        'mailqueue'
);

However I don't see where in vB it goes through and populates the array.

Basically, what else do I need to include on my page to get the maxloggedin array populated?

I hope that made sense, hah. Thank you.

Anyone?
