Forums features

I would love to use the forums plugin on my site but need more features. I would love to have the ability to do the following>

1. Create areas within the forum: eg: Discussions from Module 1, Discussions from Module 2 etc.

2. I need to be able to set notifications so I can be notified via email of new posts within the forum, and also the ability to allow others to 'subscribe' t a particular forum thread
