rep power

Hi suggestion herei know you get rep by how much you post but what if you could give rep by how helpfull someone gas been, as some people might not post much but what they do post could be really good info so you can then give them rep by how helpfull the post wasjust a thought!

we had it ages ago but it didnt work out so we removed it.

ive seen it on many other sites and works fantastic, oh well never mind!!
