Gamebattles-esgue Program

I have recently started a gamers website where I would like to hold tournaments and regular matches for my members. What I am looking for is a program like what [login to view URL] runs only a little more simplified. Here's the specs on what I'd like: *Matchmaking Area *Easily Navigated Match Set Up *Feedback/Reputation area for post-match feedback *Options for single play and team play *Win-Loss Record Keeping *I would like for it to have options for times and special match stipulations *I need it to easily incorporate with invision free forums, unreal portal, and eventually the full Invision Board License *I definately need a very easy to use Administration back-end so that I can edit any of the above listed stuff if necessary *I want it to be web based Thanks.
