Searching for plugin tutorial

[dabuki]

First, is there any vbulletin plugin tutorial?
2nd thing, I want to add an option on the permission module. Any idea how it's done?

Have a look (and search) in the Articles section. :)

A few I have bookmarked from the tutorials section:

[How-To] vBulletin API Basics: Variables, Functions, Objects (https://vborg.vbsupport.ru/showthread.php?t=98047)
[How-To] vBulletin API Basics: Creating Custom Pages & Misc. (https://vborg.vbsupport.ru/showthread.php?t=98009)
vBulletin Variables List (https://vborg.vbsupport.ru/showthread.php?t=179930)

Check out the articles forum though, there is a lot of stuff in there.
