Not trying to be harsh or anything, but whats the point of using this if you can't set the stikkits text?
When you create a new one, all you're doing is making a blank stikkit with the title as whatever you entered in the textarea.
Anyway, for those of you that want your API Key, go to
http://www.stikkit.com/stikkits, click the button that looks like this
and then get your API Key from the the URL
