You have to chat constantly

not constantly...there are 4 quarters in the day. I find that if I plurk once per quarter, my karma sores but 1 plurk a day will keep u up!

if you plurk a good resource or question and people respond to it, your karma goes up

if you edit your profile (background color, picture, description, your karma goes up

if people use a lot of fun emoticons your karma goes up

if you don't plurk at all, people deny your friend requests, you get defriended, etc, then your karma will go down.

make lots of friends, repond to other peoples plurks and when you find a cool resource, slap it up here! Try it for a wk & see what happens!
