Hi,
There is a "karma" option on SMF:
http://wiki.simplemachines.org/smf/Features_and_Options#KarmaMaybe it could be enabled, But I have mixed feelings with this.
On the plus side, it will motivate people in answering because it does feel good to get recognytions, that's for sure.
But to be honest, this forum doesn't need this it seems, everyone is chilled out and respectful to each other, even when obviously pressure is on at certain points, when one needs to deliver or "waisted" the day without any results.
I am also concerned about the wrong usage of Karma where one would get bad karma instead of giving karmas to the one that deserve it. I would prefer a system where you can only give positive Karmas, leaving the one who wants to complain to do it publicly at least, not by just pressing one button and leave... that is my main worry here. Someone that put a "bad" post knows he did... no need to remind him for life everytime he opens the forum... that's not constructive imo.
bye,
Jean
