Can you make a suggestion for a good Forum Module that I can purchase? I would like to have a user send forum discussion threads to various security user groups similar to the way the Newsletter can send to the security groups.

Once it is sent to the group, an email is sent to each person in the group so they know to open the thread via email.

When some one replies to the thread, then all participants in that group will get the reply unless it is marked complete or a particular user opts out on that particular thread.

Basically we are using this to communicate with various managers and employees on topics. They do not typically keep the forum open, so an email notification will be helpful for them to go to the forum and see responses and reply as necessary until the topic is completed.

Any helpful suggestions would be greatly appreciated.
