A good reputation system replacement?

[Razasharp]

Hi All, long time no see!

I have revived one of my vB3.8 forums, and I was wondering if any of you know about a good reputation replacement plug-in?

All I really need is something that stops those horrible pop-up confirmations after you have given rep, haha! (Or perhaps something that tells you whether you have already given that post rep or not - nothing fancy really).

I've set all rep points / power to 1, and made it so it does not go up. So it's basically like a 'like' system (negative rep not allowed). However, I want to keep it tied to the rep system because I use that for promotions etc.

Can you think of anything worth looking at?
