I've been getting a lot of email notifications about people messaging me on the site but they are not specifically replying to my listing or post. I messaged over a dozen people and have not gotten a single reply. I don't feel that people are using the site seriously or often enough to see the messages and reply in a couple days. I also feel that the quality of the people is not high enough to expect them to communicate quickly or they may have forgotten about signing up all together.
