I'm going to be using this Wiki to perform some of my tests to improve Wikipedia.
Control the rights of anonymous and logged in users through the Control Panel (which can be found in the toolbox on the left side of this page).
Add the url for your wiki to the Categorized wiki list. Simply edit that page and put your wiki under the appropriate category.
To increase the amount of space you have for uploads, add links to http://editthis.info from external sites, and go to the Link Quota Page to increase your uploads quota.
