there's some basic & complex tutorials on youtube and their forums. even for the oldest videos, the interface and knowledge is pretty much the same. you learn a lot by trial and error. the drag and drop interface is intuitive.
BAS [browser automation studio] is a competitor who is similar and free.
zenno is still getting regular updates. free demo if you're unsure about it. both softwares will take a bit of time to learn. once you master zenno you can do pretty much anything. i dont have many hours behind the wheel on BAS to comment, but saw the inspiration/likeleyness there.
