Hi Rajiv Once someone answers your questions you can then either reply to their answer on the site or send them a private message. If you would like to make friends with other Yedda users, you can add them as contacts and click on their profiles to see what questions they are asking and answering and what topics they are interested. I hope this information helps and you are enjoying using Yedda. Please let me know if I can be of any further assistance. Many thanks Debbie K
