The plain text option allows paragraphs of text to be entered with a minimum of formatting. Characters that have a special meaning in html (eg <,>,&...) and top-bit characters (eg éçù) are converted. Multiple spaces and single carriage returns are converted to single spaces, while two or more carriage returns are converted to paragraph breaks. Email addresses are made clickable, as are web site addresses beginning with http:// or http://.

There is a special format for links within a Carrelet-generated site:

http:p9

produces a relative link to page 9 of the site, and inserts 'page 9' into the text. Note that relative links are currently not checked to see if there is really a page 9, and are not recalculated if pages are added or deleted.

It probably makes sense to start creating your pages using this mode, and to change to formatted text as and when you need greater control over the layout.
