The only way I can think of is to leave a comment with a username like @NikhilMulley and then it is flagged in the inbox of that user's account(s). That can be tedious as one can only comment to one user at a time. It would be advantageous for an organizer to be able to instruct people as to how to use the site. On the site I am trying to organize almost everyone has no familiarity with the rules for using StackExchange and 13 our of 15 have never ever seen a StackExchange posting. So, it would be in StackExchange's own interest to provide a better introduction for site usage for these people, otherwise, the high percentage influx of potential new users will go untapped. Sure, I have sent people to StackExchange from social media, but, then I feel that the ball is slippery if not dropped entirely by StackExchange. How do I use this site and what should I do to get my favorite topic off the ground needs to be much more up front.

I myself, even though I am not a newbie, am not familiar with what I should be doing to get my potential site up and running. And what instructions there are are cryptic.
