I thought a lot what attribute should I give to ccBoard. Finally I left it "the" forumcomponent.
CcBoard is an easy-to-implement and easy-to-use forum solution for Joomla! 1.5. It has such useful functions like moderation, bad words filter, IP logging, captcha, avatar, ranks and preview of the posts. It can be integrated with community extensions (i.e Community Builder).
We can make more attractive our website with the usage of add-ons that can downloaded for the component: Latest Posts Module, Popular Topics Module, and a plugin with that we can search not only in the text of the articles, but of the posts too.
I highly recommend the use of ccBoard instead of other Joomla! forums. It is more complex than Simplest Forum, really is a forum. But more simple and suited to the Joomla! world than Agora Pantheon.
CcBoard is not mature, yet. It has the 0.3.0 version and it is not the real stable version. Inspite of this it is getting quickly more and more popular. Its Indian developer, Thomas Varghese connects the users of the component on his own website who give him suggestions on the one hand, help him in the developing on the other. He helps in every unique modification and customisation. The site is the demo of the forum at the same time.
CcBoard is forgetting its early bugs, it has all the chances to be the most popular Joomla! forum. Download it from here: codeclassic.org
