hey Michael,
I am sorry for any inconvenience caused.
Can you share with us where you see this link
"Find API key" so that we can correct it?
To find your API key, you can go to your dashboard
http://stackideas.com/dashboard and copy the API key, if your API key didn't generated yet, you can click that `Regenerate API key button`.
Hope this will help.
If you need further assistance, can you provide us with your Joomla backend and FTP access so we can assistance that Easydiscuss installation?
By the way, in the future you can just include your site's access once at
http://stackideas.com/dashboard/site rather than needing to keep adding them in your replies.
