Thanks for clarifying that point Bruce
Well I jumped in with the update running the beta test version 1 on one of our forums. Pleasantly the actual upgrade all went smoothly

A few minor hiccups (but more to do with Firefox 4 I'm sure). By that I mean at first the images seemed displaced on the window, but IE9 seemed to render fine! Then refreshed the window and the images and CSS all came back in normally - thought I would mention this for other "numpties" like me

Apart from that not so bad. I'm pretty certain it will be a firm favourite for current users to look at when the final release comes out
