My apologies. You didn't post a link so I assumed this was an appraisal for the domain only. Just checked out your site. Almost 3,000 posts! That changes everything.. lol
Keep up the good work. Now with the movie coming out, I'd recommend keeping the site and not selling, because if you can get a few hundred members by then, your site could explode with the movie release. (Explode in the good way!

) Could easily bring you several hundred a month in ad revenue as well.
Short term $xxx Long term $x,xxx to mid $x,xxx or more depending on growth.
