Consider adding a MOC gallery option for members to post images of their valued MOCs and share them with the rest of the BO community. Suggest postings are curated by BO admin only to ensure kids are not posting an image of a single plate, etc. :-)
Members can post with their username or anonymously (some folks are shy! <s>). This can expand the sense of the BO community... I've had multiple customers email me images of their MOCs, and the talent and sheer creativity floating around here is simply awe-inspiring (a Wizard of Oz/Star Trek mashup springs to mind a customer sent me).
Potentially others can post comments - there's good and bad to that, obviously.
