different modes?

What are the Guided and Enhanced Modes? This is something new right? Or have I been the most unobservant guy on the face of this planet? At first I thought it was something for Gollum the forumbot, but its there everytime you start a new thread.

What is the difference between the two? And how do they work?

Above the radio buttons to choose between are some clickable icons and above those are some drop down lists. Which mode you are are in affect only how those items work. Try them...the difference is obvious. And all of that stuff has been here for years. I ignore all of that stuff and just type in my tags.
