Because you're asking really obscure questions. You don't sound like you know what you're doing and to be honest it's not our job to find your direction. If you want to start a website for a complaints forums then start figuring things out. Do as much research as you can. Just asking in a forum what to do is not enough. If you don't have the tools to research or the drive then the project is doomed.
I would suggest MyBB. Its managed by a small team but very effectively. Not only that but community is growing very fast and many plugins are available for various needs.
