Wow, HigherLogic have really made a big push recently, this is the third community I'm part of that's recently converted.
Anyway, it's quite annoying that the discussions are hidden until you join a given community, it makes it hard to decide if you should join it, and also it's going to hide the content from Google which is how I come across half the posts I want to read.
Yep, I just checked with a private window and could see all the posts. https://community.extremenetworks.com/browse/allrecentposts didn't show anything though, I guess that's based on the communities you're subscribed to. Thanks for putting it in the top bar anyway.
