I finally got around to properly importing the old karma from LessWrong 1.0. Your vote-weight and the karma displayed on your profile should now reflect all the contributions you made to LessWrong over the years.
We might change this around again at some future point in time, but we just stuck with the same karma formula as the old LessWrong had, with old main posts being worth 10 karma per vote, and everything else being worth 1.
Sorry for this taking so long. Comment or ping us on Intercom if you notice anything karma-related being broken, or your karma not being properly imported.
