I received some excellent news from Russ Michaels this morning:
cflive.net is now back, thanks to hostek who donated me a server for cflive and cfmldeveloper, which will also be back soon.
Cool! I missed cflive.net. It might not be as shiny and fully-featured as trycf.com, but it has the one benefit of just getting on with it. It saves yer code and runs it. trycf.com monkeys with both the code and the output thereof, which I've never liked, and never felt was that reliable for anything other than superficial demonstrations. I have always felt happy testing issues on cflive.net, whereas I find trycf.com to be a bit of an "unreliable narrator".
The one feature I wish cflive.net would pinch from trycf.com is the ability to save code with a shareable link.
Anyway... Both services are valuable - almost indispensable - resources for the CFML community, and I'm glad cflive.net is back.
Good stuff, Russ; and thanks, Hostek, on behalf of the CFML community.
