Just a quick note... I wrote about the Guild Calendar and how it was showing up blank for me. The issue was later resolved, and I now get a full calendar of all our events. I knew it would get fixed eventually. I still wish there were more features in Armory, but things are getting better.
And more specifically, with the Guild Events... it's nicer than I thought it would be. Not only can I see my events that I created in game, but I can also see who's invited, declined, and accepted the event. Like I said, there's still things that could happen to make it better, but it's getting there.
