We are doing some updates on it, so for now, it is still not available. We are working on a system that will allow you to post things to a wall. However, you will not be able post anything personal, which includes names of people that are not publicly known, your own name, relationships (brother, sister, etc.) you may have with another user, or anything else that can allow a person to possibly identify you. This applies to this forum as well.
Sorry for all the rules, but we need to keep you safe!
