Welcome to the Q&A Forum

As a longtime user (now the owner) of a great site that was down a few times over the last couple of years I am looking for advice on how to let the over 100,000 members that have used us know that we are back and now supported fully by a team of people that love the site and what we stand for (quality, curated content and blog carnivals).  We did a complete redesign, removed old carnivals, removed inactive users, deleted lower quality carnivals, and fixed some portions of the site that were less than optimal (aka broken).  Should we attempt to email everyone, or let them naturally come back? In case it's not clear, we are from BlogCarnival.com.
