A common problem that people have when first entering content into the Web Editor, is distinguishing between paragraphs, because there is no tab in the Web Editor. Articles often times end up looking like this: http://www.treesfoundation.org/publications/article-90
This can be somewhat of a hassle for larger articles. Unfortunately, there is no easy work around that I am aware of - if you know of a program or method to automatically add the extra line in between paragraphs that were previously demarcated with tabs, please let me know.
