                        | 6 |   | Editing wiki text is easy, using any web browser and a simple [WikiFormatting formatting system], rather than more complex markup languages like HTML.  The reasoning behind its design is that HTML, with its large collection of nestable tags, is too complicated to allow fast-paced editing, and distracts from the actual content of the pages. Note though that Trac also supports [WikiHtml HTML], [WikiRestructuredText reStructuredText] and [http://www.textism.com/tools/textile/ Textile] as alternative markup formats. |
