In order to improve forum security and to preserve the identity of forum participants, we have now implemented a registration system, so that only registered users will be able to post messages to the forum. Of course, one may still post messages under a pseudo-name or a nickname (instead of his/her real name) for privacy reasons. However, each such username/nickname must be registered with us along with a password. Since a unique username/nickname is assigned only to one person (on a first-come-first-served basis), no two people can post messages under one name.
In order to post a message to the forum, a user must enter a valid username/nickname and a password.
Of course, everyone whether registered or not, will continue to have full access to read all the messages on the forum.
