[Plugin: Woopra Analytics Plugin] No place to enter API key

After having taken a look at the online documentation and examining the plugin files itself, I gather that you can access the plugin options page through the new menu item “Woopra” that should appear under the Settings menu. There should be a section within the options page titled “Tracking Settings” and your form to enter an API key would appear there.

Hope this helps.

The API Key is no longer required for the plugin.
