Show/Hide Text within a Post

[xp?]

Peace,

I have a slight copy/paste problem with my members, where they are posting extremely long quotes/articles, when they could just provide a link. I realize I could just prohibit it altogether, but to keep the free flow of information, I was hoping that there is a 'script' of some kind, or a custom code such as [article]article text...[/article]. The desired effect, is that the text between the 'article' tags would be hidden/compressed, leaving only a short 'Show' link, which would expand and display the whole article/text only after the 'show/display' link was pressed.

Make sense?

I have tried searching around, but came up with nothing. It is similar to the 'spoiler' hacks which are going around, but I was hoping that the text would be 'compressed' and hidden, so that there isn't any long blank spaces which needs excess scrolling.



By the way, I am using vBulletin 3.0.7

I have an example of what I am looking for;

This is a Long Post

Something like that, which could be generated by enclosing text within custom tags like [article]long article text[/article], would be perfect.

Thanks in advance for any help on the matter.
