Okay so I have managed to install Drupal's Chat Room Module and also got it to working fine. By fine, I mean i can post messages in the chatroom, i can create chatroom, and invite people as well. However, let's say User A posts a message in the chatroom where Users B and C are also present, the two latter users (B and C) cannot see the message posted by User A unless they (B and C) post a message of their own. I need to make the Chat Room update messages real-time (when I hit return key everyone on the chatroom can see my message automatically without the need to post a message of their own).
I have also found this thread in a drupal forum but they didn't give exact solutions for it. If you have any solutions for it, kindly let me know. Thanks a lot people. More power. Cheers.
