So i see i have ## credits.

I clicked it and it shows i earn and spend credits from creating and posting.

What are credits for?

What types of things earn me credits, and similarly, what types of things spend credits?

Is spending credits another way of saying i posted something bad? When i look at these "spend" instances, i just see posts, so i dont see why some posts earn while others spend credits.

Are there any other uses for these currencies? I also know this site has a shop, and yet there isnt anything in there useful to me.

I am sorry if this is all covered in a informal section on this site. Please point me towards that if it helps answer my questions
