too much drama for something what is really insignificant, i mean what give you the Karma? nothing its just a way to give yo a thanks for your effort NOTHING MORE, you will not come mode only for have a big karma, but maybe some people really like it as "good, good kid, go to bed" or im wrong?
NOTE: is totally ridiculous thats about the donations for karma, like some one say here, thats is for the people who dont have time or didnt want spend time posting to have a high post count to see hide topics, and more recent the people donate to have a bit more of attention to advertise their servers.
