I love Onlinebookclub.org. It's a way for me to connect with other readers and it's a way for me to find out about independent authors that I would never learn about otherwise due to my own schedule and routine. I've been active on the site for a little less than a year. The only negative experiences I have had have been when it takes an author longer than a week to reply to a review that I've submitted.
Interactions with the administrators have always been positive, I receive timely responses to any questions or concerns I have, and I enjoy the opportunity to learn about new books every day.
