One thing that I think happens in a forum is that a handful of Members supply most of the good content. It's the classic 80/20 rule. 20% of the people do 80% of the good work.

And everyone in the forum knows who those key Members are.

So it would be cool if you could Subscribe to a Member to get notified any time they post.

Or an RSS Feed specific to a Member would be a workaround option.

Are either of these two things possible?
