I just used be.live a bunch of times for a launch campaign we just did! I am extremely impressed with the quality and ease of use. There are many articles and tutorials, but to be honest I don't have much patience and yet I was still able to figure most things out. I bought 2 codes the first time and was happy to be able to upgrade and get a third this time around. This is probably the second best deal you'll ever find on AppSumo ;)
