I have a forum website. People create posts in particular topics. some other people reply to the post. but all this should happen quickly without refreshing the page. so I need to set up a chat room for that post. means when a person creates...topic a chatroom with the name of the topic should also create and when anybody reply...post via chat...also present in the...post. because chat room messages can be disappear when...is closed. but...messages stays for years. and can be readable by any one. Can anybody help me for achieving this?
