Web page addresses and e-mail addresses turn into links automatically.
Lines and paragraphs are automatically recognized. The <br /> line break, <p> paragraph and </p> close paragraph tags are inserted automatically. If paragraphs are not recognized simply add a couple blank lines.
Internal paths in double quotes, written as "internal:node/99", for example, are replaced with the appropriate absolute URL or relative path. Given a site located at http://example.com/mysite, assuming clean URLs are enabled and "internal:admin/user" becomes "http://example.com/mysite/admin/user" and "internal:node/99" becomes "http://example.com/mysite/node/99". If 'node/99' has a URL alias assigned, such as 'news/latest' the alias will be substituted giving "http://example.com/mysite/news/latest".
