I agree with your concept and even have an idea how to implement it. I signed up so long ago that I don't honestly remember the process, but I think you had to provide an e-mail address even if you chose to keep it private. If so, why can't a "Suggestions to Make Your Experience Better" file and a "Terms of Service" file be e-mailed to the new member when sign-up is complete. That serves the double duty of verifying the e-mail address and putting some useful info directly into the new member's hands.
Of course, we will never be able to "force" them to read any of it, but then nobody can argue that they didn't know something-or-other. And, if or when there is a change in either document, all members should receive files with the revisions via e-mail.
By the way, only one suggestion should involve anything unrelated specifically to trains, something like "Be civil, stay on topic, and try not to repeat what you say over and over again." (Feel free to add any other non-train related ideas you might have. Train related suggestions might be:
1. If you're talking about a trackplan, include a picture or drawing of your concept(s), include the overall room dimensions, identify objects in the area that might interfere, and identify the type of track and/or switches you plan to use.
2. If you're talking about command control. identify the system(s) involved, the hardware you plan to use, and the version of software employed as well as what products (engines, sound cars, switches, accessories, etc.) will be used with it.
3. If talking about layout wiring, include a picture or drawing of your layout with some ideas of how you would like the layout to operate.
This list is not all-inclusive, by any means, and probably doesn't mention all the ideas listed earlier in this thread. I'm just trying to suggest that your idea is not impractical and should be easily doable by the forum operator once we agree on what should go into the introductory e-mail as an attachment. Ultimate decision, though, is up to the forum moderators.
