WackoWiki

=WackoWiki= [] (in Russian and English)
 * Software systems / WakkoWiki**
 * WackoWiki** is written in PHP, using MySQL as its data backend. It is one of several wiki software projects that forked away from **Wakka Wiki** when its two key developers, Hendrik Mans and Carlo Zottman, stopped working on it in 2003. The development community is centred in Russia, and WackoWiki is popular in Russia, but works in a number of European languages. WackoWiki can be hosted using a Linux or MS Windows server. It is free of charge and open source, released under the GNU General Public License.

The emphases of WackoWiki are:
 * Readable source code for ease of development
 * A slim-featured core, with extensibility via plug-ins
 * Easy installation
 * WYSIWYG visual editor, //WikiEdit// — with keyboard shortcuts and a toolbar
 * Editors have full access to HTML; WackoWiki has a parser system (//SafeHTML//) that strips out any potentially dangerous content.
 * Supports auto-indenting, and nesting of lists, including proper numbering of embedded numbered lists
 * Fine-grained access control, on a global or per-page basis – you can define who can see, edit and comment on each page.
 * Full revision control; difference-highlighting between any two versions
 * Integrated page-commenting facility
 * Email notification of changes, with differences highlighted in the notification
 * Several levels of caching to improve performance
 * Several wikis can be run off one WackoWiki installation

Please add comments below, if you have opinions about or experience of this software system, or can point to interesting examples of its use.


 * Conrad Taylor** notes: Adrian Walmsley has experience of WackoWiki, and in fact set up a wiki for KIDMM using this software. But we never got round to using it... **¶** The formatting possibilities seem a lot more advanced and flexible than e.g. Wikispaces. For example there is nice support for citations (blockquotes); text in a floating box; superscript and subscript; terms (with definitions that appear in a floating ‘tooltip’-type box when you mouseover); footnote markers and footnote numbers (but unlike MediaWiki, their numbering and placement is not automated). The use of a double space to mark a list item can be repeated, and list items do not have to be bulleted or numbered; this allows for a lot of flexibility in offsetting text that is a comment on what precedes it.


 * Adrian Walmsley** — WackoWiki distinguishes between the right to edit a page and the ability to add a comment to a page. One could envisage using the comment capability to pose and respond to questions, knowing that users (even if they have editing rights to the body of the page) would not be able to go back and change the text of others' comments. **¶ ** However, the lack of a Captcha facility means that one cannot open up the commenting facility to unregistered users without the system being flooded with automatically generated spam comments.
