I went through the same thing. I'm not sure what it means to "suggest" a workflow. I tried both of the extensions and just couldn't figure out how to build a workflow for myself, and couldn't find anything like what this blog post is talking about :-/
I am sorry I think you might have installed the our workflow plugin(close ended agent) instead of agent4 (open ended). Its a new experiment we are working. We are working on the website messaging.
