In the Planner's Community there are links to navigate between Discussion spaces & the Blogs:
But in Project's Community, that's missing even though it does have a blog, too (although the technet blog which is more active is linked in the announcements).
Also, @Brian Smith, gotta say, I love the "More Resources" box on each Community's page. Kudos to whoever put them together. Now if only those external resources would link back in an obvious way :)
Thanks for the feedback Ian - @Anna Chu can you help us get the same links in the Project community as we have in Planner - to the Blog? And @Ian Bruckner Anna is also the person to thank for much of what you see in the Tech Community!
