I know you're joking, but I can't tell for sure if you're half serious. A check box for "I have read, understand, and accept the terms of this usage agreement.", where the usage agreement is that we will post, to our best ability, clearly-phrased questions with suitably formatted relevant code would do as much good. If you have a captcha and a captcha entry box, it only means one has to glance at the page rather than reading it.
The clearest way to get points across to people about to post is to not refer them to another document at all. Pick the two or three biggest problems to address and address them directly. Have a link only for more information.
Before you post:
- Is your question or issue specific and complete including a searchable title relevant to your post?
- Did you include a small code snippet (in <code></code> tags) that demonstrates your problem or question?
- Have you searched for answers with Super Search, Google, and in the Perl documentation?
- Read How do I post a question effectively? and the documents linked from there for more information.

Then,
How do I post a question effectively? could reference all the other stuff, such as how to make a title more effective, where to post, how to use PM markup, how to ask questions more effectively, and more.
