Info on Ed Brill's site, downloads from PartnerWorld etc atm.
Currently downloading it, looking to upgrade infrastructure at our workplace (I went to capitalise that by default!) within the next few months. Why, given that I'm moving to ASP.NET? Well, just like the amazing rubber man, I'm doing it "because I can". It should be fairly quick and painless, and I figure I might as well do it now rather than later. It'll put me in an interesting situation of interoperability though - once we're all R7 here (which won't take long), it'll mean I'll have R7 for "our" stuff as well as my dev server and home stuff (for as long as the latter lasts), R6 for 2 clients, and R5 (yes!) for one client. What a pain in the ass.
