Optional Article Author Information

[TimothyGillespie]

A partial, but pretty developed solution for this can be found and reused in #50.

Currently, the article author is not an information that is recorded or displayed.

This task would be done when:

• The post model is enhance with an optional information on the author
• The author information can be stored and displayed
• The author information is added to the bottom of the page according to the initial design (attached)
• The short author information is added on top of the page (also see attached design)

Nice to Have:

• Allow to specify other contributors, for example for reviewing article, giving suggestion, idea givers and credit them
• Allow multiple authors
