The information in this wiki hasn't been maintained for a good while. Some of the projects described have since been deprecated.
In particular, the "Ushahidi Platform v3.x" section contains information that is often misleading. Many details about this version of Platform have changed since.
This website is an extraction of the original Ushahidi wiki into a static form. Because of that, functions like logging in, commenting or searching will not work.
The instructions start with renaming the directories for each plugin... the new names for these are: taskingsystem, tsgeolocation, tsfilter, tscategorization, tsapproval, tsstructure. There are no instructions to rename TS-Anonymize.
Go to your Ushahidi website, e.g. http://www.myushahidi.com/, go to the plugins page (http://www.myushahidi.com/admin/addons/plugins) and activate all the tasking modules that you want to use. Activate the "tasking system" plugin, click on "settings" and have fun. Plugins aren't too difficult to build once you get the hang of them, so if you need other specialist modules, you can always ask the Ushahidi dev community for help.
