Send generic email notifications to recipients of new/updated conversation messages to alert them to check the site to view the message.
"You have received a new conversation post from userX on mysite.com. Click here to login and view conversation."
I am building a new communication resource for existing members of an organization who are happily creating long and cumbersome email chains. Once the email chains are abandoned, no one goes back to see the conversations we had. They're difficult to find there. But, convincing my members to use conversations instead is impossible when they aren't being alerted to check in.
Also... I need to figure out how to set up the mobile app. That may fix this problem for those members who have smart phones and are willing to download the app.
