feedback site(repost)

The website that I want to have created is going to be like <[login to view URL]> . First, go ahead and study it and see how it works. I want something similar to that. You can suggest platforms/pgmming languages for the optimal site performance. It should be able to handle about 50K users. I will also need an admin section for me to be able to delete/modify feedback. Also I should be able to accept advertiser banners. They need to rotate at a random order. That's all I can think of right now. I will post some more, if I get legitimate questions. ## 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.
