Forums are a must-have feature for a community site. A forum is a collection of topics containing user messages. Using Tiki you can configure as many forums as you want and establish permissions to determine who can create forums, admin forums, create topics, post messages, vote on messages, etc. Individual permissions can be set for forums so you can have private forums only visible to some user groups. The forums section in Tiki has many advanced features such as auto-prunning to prevent the base of messages growing too big, flood-preventing, sticky topics, locked topics, etc.
