Whether I try to save e-mail options through the /groups page or by clicking 'E-mail Options' in individual groups, preferences are immediately lost.
The other issues I've got are mostly cosmetic, but this renders the plug-in worthless for me. It's gone awfully quiet in here, but I'd happily buy a coffee for anyone who could help me work through this. Or if this plug-in is flagging, does anyone know of another one? My users are missing out on too much content by having to actively click the 'Groups' tab to keep up.
