Avoid showing "Quote" button on 1st post of thread

[gringo]

Hi. I hope to be able to find a solution to this nuisance. I have to qualify that nuisance variable. I am sick and tired of members quoting the first post of a thread since we post longish tutorials on that post, so we'd like to avoid people quoting said 1st post.

Is there a plugin, script, etc, that will hide the "Quote" button from the first post of a thread ONLY?

Thanks very much for your assistance.
