Absolutely, sign up if you get invited! D has found a whole new group of very smart friends. They have gotten her interested in Latin, neuroscience, philosophy, and reading more classics. Sometimes she spends too much time on Cogito when she should be studying, and there is occasionally some drama when members have family problems or issues that they bring to their online friends. But she made a very good friend who lives in our city, and they have gotten together in person. D does not make friends easily, so it has been great for her.
