Hi, im kind of new here, and ive been wondering how to give karma, and if possible see whose +1/-1ing me
After a certain amount of posts, you can start giving out karma (I was able to after about 200 posts). As far as I know, you cannot tell who has given you karma.
There is currently no way to see who has given you +/- karma, or which posts you were given it for. Generally speaking, if you want good karma, just be kind and helpful in general, and the community will reward you - we're pretty generous people. But we're not saints! Spam, insults, ignoring forum law, and rudeness are all things that are likely to send negative karma your way.
