A Forum quorum: 

• A forum is an online discussion site where users share ideas, thoughts, or help by posting text messages.
  • In other words, it’s an area where people can hold conversations via posted messages.
  
  
• Forums are not the same as chat rooms since posting message does not happen in real-time, and users can read these messages at any time.
  
  
  
• Moreover, unlike in chat rooms, messages are often longer, and they are temporarily archived.
  

• Sometimes, a moderator of the forum reviews and approves users’ messages before posting them.

• This depends on the set-up of the forum and the access level of the user.

• Furthermore, users may have to register in the forum and log in to post messages. Some forums may allow posting without registration.
  • Generally, users do not have to log in to read messages.
