Hi, I'm Jens aka Yodahome (since this nick is free in most cases). I'm using Wikka Wiki now quite intensely for about three years and made a number of changes for my special needs of which some might be interesting to others as well. I included many extensions offered here on this site but also changed some of them as I saw fit. I try to put up some of the more interesting tweaks. My Wikka runs under http://yodahome.de/wiki but I also use it as kind of an CMS for my websites http://www.littlevampire.net, http://yodahome.de/hacker and http://yodahome.de/fightclub (under construction). For a while we used Wikka Wiki for the website of acagamics(.de) where a phpbb-forum was tied in so we had one login for both services and could view rss feeds from the forum inside the Wiki. Furthermore I established a Wikka Wiki for the Gamesgroup at Magdeburg university (games.cs.uni-magdeburg.de/wiki ).
I've just finished a job where I ported a static website to Wikka Wiki for easier maintainance. (http://absolutartist.de) It's a pretty neat CMS in my opinion.
Furthermore I'm studying media literacy with a special interest in so-called "Web 2.0" including social software and semantic web. This is why wikis are even more interesting for me in a scientific context. I hope I can find something among those topics to write my thesis about.

Stuff I work on:

FreeCap


CategoryUsers


Ajax enabled


Right now I'm experimenting with some AJAX-related tweaks to the Wikka. E.g. I think the comments could be thrown in using AJAX so you don't have to reload the whole page. Apart from that it should be possible to blend out menus if you don't want to see them. Ultimately I think content should be loadable into the body section without reloading the page. But I don't know how hard it would be to implement this (though I'm tryin'). I also try to integrate widgets of web 2.0 services to wikka wiki.

My first enhancement with ajax: AjaxGallery
A second approach: SlideshowGallery

WikiEdit


Since version 1.1.6.1 of wikka still used WikiEdit 2.15 I decided it might be a good idea to upgrade to the latest version which was 3.01 at that time. I took the fresh files and -hopefully- changed all the stuff to make it work with wikka again and also made some other changes to it for my personal wikka. One of those is a third button for headings (h4) which I left in this script since it might be useful for others as well. This is not really tested with the latest release.

Installation:


WikiEdit is located in your [wikka_base_dir]/3rdparty/plugins/wikiedit. I recommend to backup the whole directory (just in case, I actually just renamed it). Then you can either load the whole package from http://wackowiki.com/WikiEdit or you load the already modified package I attached to this page (I suggest that). If you do it with the original package you need to replace the wikiedit2.js with this modified version and add the h4-icon as well.
I use this on my Website and it works fine but if you encounter any errors please let me know.
