Multi Site Network Admins (whether a group member or not) can successfully send Admin Notifications (group>admin>email options) - It's a great way to email all group members.
Group Admins, that are not Multi Site Network Admins, are not able to send a Group Email Notice with this plugin on my sites. Submitting the form results in a page refresh and no action is taken - no error is generated.
The main function of this plugin, mail notifications of daily/weekly group activity, works for all group members. The problem seems limited to Admin Notifications (for non-Network Admins). I've replicated this problem on 2 WP installs. Can anyone confirm this problem? If not, wondering if this is an issue with the configuration of my server or if this is isolated to Multi Site WP installs.
