This adds the option "Anti-Spam Setup" to the administrator's menu. This menu enables you to set up the configuration for this plug-in.

The edit the configuration, do as follows.

1. Open the administration menu.
2. Open the option "Anti-Spam Setup".
3. Here you may activate a so-called "CAPTCHA". This option display a graphic with a text, which the user must retype in order to be allowed to submit a new entry. (see figure) To be able to use the "CAPTCHA", the PHP GD library needs to be installed and support for PNG needs to be activated. This should already been done for any current standard installation of PHP. If for some reason this is not the case for your copy, please request your administrator to install the missing library. For most providers this shouldn't be much of a problem.
