517038 Chatbox Script

Hi, I am looking for a chatbox script developed and intergrated into my current script (PHP). I'm looking for an exact clone of the chatbox script seen at [login to view URL] Please make yourself familiar with the Points2Shop chatbox script before you bid. Requirments. The script should be developed in a mixture of PHP, Ajax and javascript. I don't know the best method of developing this but the site could have hundreds of people online at once so it must be developed efficiently as I don't want a constant strain on the server. I would also like the chatbox to be in real time with a max 1 second delay between posting and another person seing your post. Users will be required to login to post a message. Users should be able to see the last 50 messages with a further option as seen on Points2Shop to view the last 150 messages. I will also require the script to be easily integrated with css/html code Gobal View Display Username User Type (Admin,Mod,Newbie etc. Color codes for different types) This will be stored in a database table Country of user. This will be stored in a database table Time of post Message Ability to add Admins/Mods Admin/Mod View Settings Ban user from chat Ban IP from chat Temporary ban user for 10 minutes Delete post
