Recognized means it will appear on all the appropriate listing and also the site search engine.
A post is considered for this status after it has received 15 comments (anonymous comments do not count). Once eligible, it is considered at the end of each day.
When recognized, the work is moved onto the category listings and the ribbon shown here is displayed by the work in the artists's profile. The artist will be notified by a private message.
The site picks works by looking at the ratings and the members that commented. All comments count, but good ratings from members that have earned blue stars (the more the better) carry more weight.
