Well, not an official version but now thanks to lots more help from tvn which ended in me updating a bit of documentation on how to customise group pages as it was out of date - http://drupal.org/node/1187094
Have a look around the tabs and click on the quick links, this is the best I can do for a start. There may be a way to get latest issues automatically listed, we're looking into it.
In the mean time, if you look at something and see it could be better, if you feel something could be better, or indeed if you hear of something which could be better please immediately go file an issue in this infrastructure section and I'll look into it. If you don't, it's highly unlikely anyone else has been through exactly the same life experiences as you have and come up with the same vision or feeling so post now or it'll never change, until you remember and decide to post.
Anyway, enjoy and I'll check back in later, off to our weekly freelancers meetup http://brightonfarm.com to chew the cud and chat more Drupal :D
