We run NT largely as we run our forums for Psych Central, as a part of our mission to provide a supportive, self-help environment that allows people to help themselves. So much of health and illness is just learning as much as you can about it and discovering you're not alone in this journey in life. Others have come before you and will extend their hand (and their hearts) to help you through it...
The costs to run even a large community online (50,000+) are minimal, as long as it is well-managed and well-maintained. So minimal, in fact, that you'll notice we don't even bother with advertisements here...
We do have experience with running larger communities online, so we know what to expect and how to manage the growth without impacting the free services we offer our members. We're here to support you and will let you know if a specific need ever arises.
Thank you for your continued support and for choosing us over the many other choices you have!
Best,
DocJohn
