Interesting perhaps these are Carver Culture markers placed over spacetime anomalies . Else perhaps the Carvers sculpted the rock using such exotic forces . Very exciting , much to think about . <| sep |> Hey everyone , My sister and I have spent over a year developing this app and we would really value any feedback people have for us here . The app was designed to help people to Save Time Organising Any Group Activity . Our motivations for creating the app were to develop a platform that facilitates people interacting in real life we have more ideas to make the app better for this but just started with the simple aspects of organizing meeting people . It would be great to have a discussion about it with people here to help us improve it . Thanks !
