The ability for people from all over the US or world to see who they met at church in person so you can see where someone lives and what their interests are! It is great because I have been able to stay connected across states since before it started using this program!! It also has other benefits of having more time available to focus on one's job rather than constantly keeping up w/ technology. There isn't much dislike about guestview as long as u know how things work and get used quickly! We use our own website (www.admissionguestbook.com) but we realized many people don’t even realize there is an option like this online which would be helpful when trying to find them after meeting them through your church services.
