Hi, i have a social network that i wish to give the users an option to chat 1 to another.
i was thinking about doing it myself using a database & an AJAX function that check every minute or so if there are new message, but i worry that this is too simple for large scale networks, therefor i would like to hear any ideas on the subject & reccomendation on available scripts & apps , so i can learn from them.
Cheers
