I am confused!

It is simple. If you write a post, you get paid. If you respond to a post, you get paid. It does not matter where you post, but you do not get paid for the comments you make to the responses people give to your post. Mylot does not like violating terms and that is the only thing you have to be careful. You will also get paid when you upload a picture. It is usually best so the responses do not come in one or two word sentences because people and you are trying to find the solution and you or they might want details.

when someone responds to your discussion-- you earn and when you respond to other discussions you still earn regardless of the topic
