User Reputation Help

[whealey]

I'm not sure if I am allowed to post this type of question in here so feel free to remove it if its against the rules.

I have been searching for about 2 hours looking for an alternative to the user reputation feature. I have come across the 'Thanks Hack' but my forum users don't seem to like it very much.

Ideally I want a button on the top of each post which says 'This post was useful' and then it builds up the reputation of users. I don't want a negative reputation option as people have been using that simply because they don't like the topic which is being spoken about.

I really like the way the Apple Support Forums do it - its very clean and to the point.

Any help with this would be much appreciated - cheers! Will
