Looking for a chat room on my site

Hey guys I want to make an actual chat room on my website: [login to view URL] The chat room can be done in java, or flash, or I am open to suggestions from the coder. I want the users to be able to login using their username that they login to the site with. We can do this by only allowing hte page with the chat room to be viewable by members, or we can have the coder tap into whatever files are needed. the chat room should have a who's online list, and "click right" options to interact with those users (links will be supplied for this) ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform server is linux if that matters
