Here is a link to the KGB area of Spectrum.

Seems like an awesome start; combo chat/forum + more coming. They mentioned a lot of "upcoming" features @ CitizenCon 2016 in the 3.0 reveal video. Talking with the devs there - they will have a lot of ties into the actual game to Spectrum vs just a stand-alone forum type thing.

The link doesn't work. I get a 404 page not found error.

Try logging into your RSI account 1st Owain then clicking the link. Interesting setup the new site has.

Yes - I don't think you are "allowed" to see the site unless you have logged into your account first.

Indeed - definitely interesting; after watching the latest ATV, going to be getting better and things added over time.
