I've set up a virtual machine with Diaspora as a test box for a social network tool for our team.
I think that I'm using the correct terminology here, please be patient with me if I am not...
We currently use Google+, and team members can post to the shared Community. Everybody in the community gets an email alert when a new topic is started on the Community. This is a key feature as people do check emails regularly, and this way we can ensure that they will not miss a post.
I can't see a way to configure that on Diaspora; we can get email alerts when:
...you are mentioned in a post?
...someone comments on your post?
...you receive a private message?
...someone starts sharing with you?
...someone likes your post?
...someone reshares your post?
Is it possible to do this with an Aspect (and/or a hashtag, possibly)?
