Question

you may think that this question should be on Meta SO but it should not, since it is basically about ASP.Net MVC but the technique I want to implement is already implemented in SO.

I want the users to have power while they gain more reputation just like the way we do in StackOverflow, and my question is how to design the user authentication system? Can we rely on the built-in Forms Authentication? and how to manage what links (depending on the reputation) to be shown for the user and what is not?

I think we can’t use Roles here so we don’t end up with 1000 roles, right? but we may use 2 Roles (Admin, User) only.

[Edit]:
I think it is better to create my own Users table rather than depending on the Forms Authentication, and so I can add reputation field (and other fields) to the users table and track it like you said. BTW @MartinHN, I know about the if you talked about, but my question is there a smarter way to handle such matters?

Answer 1

You could create a simple rule system. Each user has a reputation score associated with them. Then, using an action filter you could control access to functions in your system:

public class SomeController : IController
{
    ...
    [ReputationNeeded(Reputations.CanVoteDown)] // your custom action filter
    [HttpPost]
    public ActionResult VoteDown(...)
    { /* */ }
}

Good luck!
