 1 | 
 2 | I wanted to use the Random Page plugin for DokuWiki:
 3 | 
 4 | http://www.dokuwiki.org/plugin:random_page
 5 | 
 6 | But it didn't work.
 7 | 
 8 | So I poked at it a bit... and now it works.
 9 | 
10 | (I even fixed the URLs it returns.)
11 | 
12 | Jean Marc Massou did all the original code, I just cleaned it up so it would work.
13 | 
14 | I did email him about it, but I figured I should also publish the code in case someone else wanted to use it.
15 | 
16 | I also changed it from being named 'random_page' to 'randompage' 
17 | 
18 | (Hooray for open source.)
