Would it be possible for the "latest activity" indicator to be a link straight to it? When I check the activity on my groups page, I see "latest activity 20 minutes ago" or the like, and it would be great to go directly there, rather than scrolling through things I've already read.
I'm really enjoying this site, and it's cool to see how many people join on each day.
You can link your discussion to your email and that gives you a direct link to the latest comment. Once there you can continue on the site and return to your email when you are done with a simple click.
