There is a section on my site, where users can submit content.
I'm not sure how to call it.
There are three cases:
1) user can submit own content, so he could be an author
2) user can submit thirdparty content, so he is just a submitter
3) user can submit both his and third-party content.
First case - call him an author or contributor, that's ok.
Second case - submitter.
What do I call a person in the third case? In this case he could either an author or a submitter or both. Is there some middle word, that can describe both ways?
Is there some better word, similar to the meaning of submitter?
