We're looking for private internet chat room whereby up to 15 people can log on (username/password) and enter their comments/opinions in real time to questions posed by a moderator. The whiteboard facility should allow the moderator to upload photos/videos (e.g of products/ads) for discussion. The system will need to keep log files/transcripts of each persons comments. It will need to allow for several projects to be run simultaenously and we would need to be able to host it on our website. Not sure of the most appropriate development tools to be used and am open to suggestion.
