Absolutely nothing -- and that is what is supposed to happen.
We do not give notifications of editing actions.
You did your part by suggesting the site, and you received an immediate on-screen confirmation when you did so. That is the last you will ever hear from us.
We in turn, will at some unspecificed time, review your suggestion. If we accept it we will tell the entire world (by the very act of listing it). If we don't list it, then there is nothing to anounce.
It is all really quite simple.
