I installed this plugin and there's no tab at all showing up for the e-mail notification. Now I believe this is probably my fault - I added some code to my BuddyPress theme to get rid of the "Home" tab and so that when you click on the group, it automatically loads the Forum tab. I bet somehow that code is interfering with this plugin, but I'm not really a coder so I'm pretty confused and would really *like* to have e-mail notifications.
(I realize this may be really unhelpful without the code itself so if that is needed I will figure out what I changed and post it here)
Any guidance would be great!!
