Posting Code Question

[MoB Dudditz MD]

I have noticed that the license feature works when using the CODE BBC
but if I simply post text, it will display to unlicensed users.
My question is:
Are there policies and guidelines when posting vBulletin code in the forum?
How much code are we allowed to post?
When submitting a mod or hack, is there a limited amount of vBulletin code
that is allowed to be included?

I was wanting to begin a vBulletin discussion in my own board.
Are there restrictions I have to follow as far as posting code for public view?
