php chat system(urgent)

There is an existing open source project that is very similar to what I want, you may use their source code and modify it or start from your own code. Basically, I want a very simple message client, like an internal twitter.com. Here is the template for what I want, I have the css ready for you to integrate. [login to view URL] here is a project which has source code available: [login to view URL] I would like to use php and mysql and have very well organized code because I intend to release this as an open source app. Features -user login, very basic profile -Discussions (each button at the top is a different discussion) different discussions may have different sets of users) -archive (shows daily chats) -search (searches any text stored in archive by day, month or all time) by default search should search just the messages in that discussion page - click user name to get history of their messages and user profile - main messaging functionality -password protection so people typing the address cant search or see messages unless they are part of the group - easy install wizard like [login to view URL] that people can use to very easily install this on other servers. It should work like a [login to view URL] install, something automatic and simple. ## Deliverables i will provide deatils when any coder selected on this project ,
