Is it Allow public anonymous?
Hmmm…this is interesting. I can see the “turn off email” in the plugin code at WordPress and I can see it working in my main site at https://speakout.123host.net.au but I don’t see it in a development site I use.
I am going to do some testing and will update you
OK, I have found the problem and I am a bit confused by it.
That option is hidden using CSS, I am trying to think of why I did that or if it was something left behind in testing.
If you open /wp-content/plugins/speakout/css/admin.css and right near the bottom at line 215 you will find
.dk-speakout-hide-email-option{
display:none;
}
Change the word none to block. I will update this in the next version, but it will work fine for you until then.
Note that if you enable “don’t collect emails” it can’t be reversed.
