Please take a look into this.
I just barely noticed it on my site at Salt Lake Examiner
I tried setting the send button to "No", saving, then setting it back to "Yes" and resaving. This did not help. I also tried to disable and re-enable the plugin and this did not work either.
I Should note that it did work in the past but no longer since the last update I think. Please let me and others know what we should do or if you're aware of this and are working on a fix.
This is a great feature and I would love to see it work.
