Thank you. Yes, I understand that the plugin will "replace" the corresponding hook in the php file with my plugin code. But before vBulletin loads that said file it also loads a number of others, where objects and variables are initialised, creating a working environment for my plugin. I am trying not to reinvent the bicycle by querying the database for the data that has been pulled already and is just sitting somewhere in an object I don't know about. That's what I am trying to figure out - how do I know what variables and objects are created by the time my hook is pulled up. I hope vBulletin provides some documentation on this and not just "go through the code" advice, although either one is appreciated.
