Emails not being sent and no captcha displayed
I have installed the Addthis plugin at http://o2e.org/j16-1/
When one uses it to email a link to a friend, it states that it has sent an email, but no email is actually sent.
I notice that, unlike when I use it at http://rational-ug.org/events/webcasts/c/e/132.aspx, on the o2e site I do not get asked to fill in a captcha of moving letters.
I have checked and the emails are not arriving and ending up in spam.
Can you help?
