I have seen the status shown on every person account, either online or offline. But, I don't find much difference between the two. Because, If we order a service, We would like to have some interaction with the seller. So, We will check him, whether he will be online or not? If it shows online, we will send a message, But, We are not sure, whether the person checks our message or not? Its better, if SEO Clerks introduce to make people know, whether their message has been seen by the other person. And it is necessary for a high rated seller to reply to their buyer's message, to continue his ratings. Otherwise, degrade his level. So, How many can support this thread?
