Since my last post on this forum was met with the sound of crickets I thought I would give it one more go.
I recently upgraded to 5.04 and all seemed to be going well except for the relentless daily assault of comment spam my blog has been receiving recently, like thousands. I finally decided to take advantage of the already installed TypePad AntiSpam plugin that everyone raves about. I got my API key, logged into my dashboard, clicked on Tools > Plugins > Typepad Antispam, and then clicked on "Settings" so I could enter my API key that activates the plugin, but there was no field to enter anything into. The only thing listed under settings was "Junk Score Weight" and a drop down menu. I thought I must have missed a step so I followed Typepad's instructions again and again and got the same result. I then tried reinstalling the plugin to no avail. Any ideas that might remedy this?

Use the global Settings for Typepad Antispam at System Overview --> Plugins. There's a field for the API key there.
