Each time you respond to the expert you choose, you will have the opportunity to continue prompting for more experts within your selected topic, or move on to a new topic altogether. Once you pick a different topic, a whole new list of experts will appear for you to seek advice from. You may change topics as often as you like, provided you respond to each expert you select. Feel free to explore the various topics in whatever way seems most comfortable to you, and remember, the more experts you talk to, the more you can learn about the design problem you are faced with. Our goal is to solve our problems, but first we must understand them.
