I’m currently working on a chat feature for the Wildlife Focus site, which is run by the World Land Trust. Since this is a charitable organisation doing great work, naturally I am doing this for free.
The initial requirement is to allow registered users to be able to post comments on the webcams that are being displayed, allowing them to discuss what they see etc. In the future it will be integrated with PHPmotion, which the site uses to show user uploaded videos, allowing live discussions.
I’ve only started it, but have got quite far already. It’s being built with PHP, AJAX, MySql and of course HTML and CSS. I’ll keep you updated on how it’s going.
