One of the nice things about writing in the FedWiki is the mobility of paragraphs (and a whole lot of "paragraph-like objects").
All you have to do to shift a paragraph up or down in a page is click and drag. If you want to move a paragraph from one page to another page in the same site, simple click and drag. If you just want to copy the paragraph to another page, shift, click, drag.
Sometimes it is a little annoying the ease of moving paragraphs. You quickly learn to scroll pages at the very edge.
