I'm working with the GROUP CATEGORY LAYOUT where I want my users to enjoy the activity stream showing them what's been going on in all the groups.

Trouble is (link provided) lots of stream entries says "xxx joined this group" - Can that be changed to show the group name, so "xxx joined the StackIdeas Appreciation group" with a hyperlink?

As it currently stands the 'this group' is not even hyperlinked so it's really a pointless entry when looking at the group category layout stream (it would make sense in the individual group.. but if it had the group name and hyperlink I suggest it would work fine in all scenarios)...
