Site looks great overall. I'll echo many of the minor little criticisms others have made, and add one more:
I don't think the staff gem icons are distinctive enough. Staff members don't stand out enough compared to regular members anymore. Sometimes for various reasons it's nice to be able to catch a staff post when quickly skimming through a thread, and it's much harder now.
EDIT: Also annoyed that my health globe on my profile pic turns green whenever I am online, but oh well
Looking amazing! However, one thing I noticed on the "Stream" section is that when you click on a live streamer, the page is a bit odd looking(Video is not centered etc.). Granted it's a simulation of Twitch's page, so for a simulation it looks amazing!
On another note, the white color around when a person is typing there message, is very bright (Text entry box, "where I'm writing this text now", whichever). You guys captured the essence of the new style of Diablo 3, but since everything is such a dark contrast, the white is a bit blinding. So changing it to an off color tan, or the same color as this text, would solve the issue!
Other then those two things, frickin amazing job!!!! Give your developers a huge pat on the back, and a six pack of beer.
Is there any chance you could widen the blue tracker to show full titles? I have this 16:9 monitor but barely get any information on the home page. Showing more than the 4 more recent blue posts would also be greatly appreciated.
Also thank you for bringing back the flags on them to denote whether they were EU or US posts.
