==Abstract==
While you are editing Abstracts should be placed in the articleExcerpt box, there is a box labeled "Optional Excerpt" displayed a little ways below the "Post" field. Put If you do not see the Excerpt box, look under "Screen Options" in the top right of the page. Selecting the down arrow will display fields to show on the screen. Make sure that 'Excerpt' is selected. This will display the Excerpt (abstract here) input box on the page. Use HTML markup as appropriate. What you put in this field is what will be distributed in our syndication feed and what will appear before the article as the abstract.
Assigned editors are ultimately responsible for a good abstract. Authors aren't always the best at writing good abstracts for their articles, you should probably revise or even write a new one from scratch as necessary, even when the author has provided one. Some of the abstracts for my assigned articles haven't even mentioned what I consider the most significant features of the article.
