Where can I find internal vbulletin documentation?
 

Hi,

Where can I find explanations about things like '$this->tag_list', creating hooks, etc ?

I want to write my own plugin, but I can't find any decent developer-documentation.

Any help ?

Read the source :)

Hmm... Could you point me in the direction of the right files? (for the tag_list)(I'm more or less starting from an existing plugin)

vBulletin API

Else read the file that contains the hook you want to use.

Thank you, that was exactly what I was looking for.

And how would I know which hoock I would want to use for a specific purpose? Is there a list or something?

Common sense, trial and error and a bit of luck. Check the PHP code if you get completely lost.
