Currently there is no way to search for other users on the site. However, it is a feature that we know a lot of people are interested in so hopefully, at some point, users will have the ability to do so.
Hi, Staytrill. If you find an answer of that person, you don't have to type in their name. Just click on their name and it will take you to their profile, when you get there, just click "follow" and that's it!
