Posting on community?
Not entirely sure this is a bug, but I've had a few problems with posting. Just now I tried posting something, and it didn't register immediately when clicking post. It then proceeded to keep the text box (for writing a post) on-screen and did not register a post on the stream. I exited out and the comment had posted.
Not entirely sure if this is a bug or just a problem with my computer/internet, but I thought it would be worth mentioning.
