TardSeeker added a post in a topic: Is anyone using Nexus yet?
Yes people are using Nexus. They had bought it in one of the two presales.
Yes it is still in beta, so unless they do a third presale we all have to wait for it to be released.
It is on some people sites already, so I am sure if you do a google you can find it there, or someone can link you their site to show you how they are using it.
Unfortunately even though I made an order for Nexus during the pre-sales it never went through for some reason, so I never got a copy :(
