Currently running a Beta test - Would be great if you try it out. This phase will extend for one or two weeks only, to check stability and test a couple of new features/add-ons. Expect hiccups.
On the site we provide a high-level explanation and a slightly more detailed discussion, all presented in an accessible way.

I'll be around in any case to answer Qs.
