Connect: Groups vs Forums

Connect: Groups vs Forums

Hi,

I am struggling to understand the key differences or rather benefits of Groups vs Forums? I can see that forums work at network level and groups can be restricted/controlled to specific members etc but the functionality seems to over-lap. As Groups can be linked to mail, events & tasks etc, all of which can flag up on the Connect activity feed, I don't see the purpose of using forums at all.

It's fine having a function unused but I want to ensure we are not missing something key and the knowledge base is very limited on the use of forums other than how to set them up etc.

Thanks

Andrew
