The forums are enabled by default on your articles @complement@ and they are deactivated on an individual basis... Visitors can then react to your articles... You will be contacted by email each time a message is posted on one of your articles. Small flip side : spams which are not always easy to identify and that sometimes you need to manually manage. To process a message forum message (remove it if it does not please you or report spam if it is one) :

• In the public site on the page of the article, if you are identified, there are two buttons "Delete this Message" or "SPAM"
• In the private area, via the activity menu / Manage Forums
