Is it possible to give some sort of notification or send an email for unanswered questions or posts?

There are a couple ways to do this, each would require some custom code be written.

• A plugin that handles the Forum Thread Create event and schedules a job for 18 hours later that could check if any replies have been posted and send an email if not.
• A job plugin or automation that runs on a schedule and does logic to fetch forum threads and check for any that are over 18 hours old with no replies.

It would be more difficult to customize the content of the notification if done via automation, as plugins can specify ITemplatable and expose a rich text editor for adjusting the notification/email content.

On the second point, the automation, I'm looking at possibly building this out with our Prof Services team to give back to the community. Will have to see where we can fit it in.

Would this notification fire *every* 18 hours a thread remains unanswered, meaning the same thread could fire notification several times? Or would you expect only one notification per thread?

Who receives the notification (you mention a specific email so set a configuration option for  that or create a user with that email)? Should we also base it on a role that you select? Would the OP get something as well to let them know its been bumped?

Anything else we aren't asking?

My 2 cents since I would also like this functionality:

I'd expect one based on a configurable time (I'd personally expect 24 or 48, not 18 hours), but I could see different needs for different communities -- case deflection-focused communities may need shorter time limits.

I would see this being similar to the user/role dropdown in Reports, where you can include either specific users or specific roles. For example, if this was a product-specific group, you could choose a "Product A moderators" role, or, if there is only one Product Manager you want to call out, you can choose that specific user. I think being able to specify a specific email address would be helpful, e.g. "support@company.com". 

Alternately, it could just go to Owners / Managers of the group and it becomes a moderation responsibility.

I vote no, or make this optional. This would feel like when you're listening to hold music and the voice comes on to tell you "thank you for waiting." OP would get excited about a reply, just to hear that it's a reply saying they're still waiting.

I would see this as an automation that you could configure on a per-forum or per-group basis, so a community may have multiple versions of this firing, versus it being site-wide for all forums. As mentioned above, each group or forum may have different needs.
