1. The messages we type and send to anyone aren't stored anywhere means the conversation history is lost every time we chat 

2. My cron job is configured to run every minute. I have also checked it using the plugin cron test and it works fine, but, this plugin takes almost 1-2 hours to change the status from online to offline after the other user has closed his bowser!

3. Smileys don't work with this plugin.

Please resolve my problem as soon as possible.
