But how do you get the newbies to read this?
I don't know, but they NEED this, especially that part about this not being a blog and about not posting vanities.
How about we take away their first-born until they can pass a multiple choice exam?
You can go to their first posts that are vanity threads, and mention that vanities aren't all that cool. Then you'll be jumped on by well-meaning Freepers that think you're being a grouch and not welcoming the newbie.
Personally, I'm almost ready to post a vanity about my upcoming dental teeth-cleaning appointment and I'd bet it would get 100+ sincere replies.
