vB4 Which GLOBALS could be used in plugins for global_start hook

[محروم.كوم]

How and which global variables could one use in plugins in vb4?

I am trying to adapt a 3.8 plugin into vb4, which replaces forum titles globally everywhere.

For instance depending on value of $vbulletin->userinfo[languageid] forum titles have to be changed using

Code:
$vbulletin->datastore->registry->forumcache[$id]['title'] = $NEW_title['title'];
Where $id runs all available ids of forums __DEFINE_LIKE_SHARE__
