No big deal guys. Discourse is a open-source forum software. Based upon feedback from their user community (which continues to grow quickly) about what is used and what is not used, they make decisions about what will continue to be included in the core feature set. In this case the daily email summary functionality didn't make the cut.
Our forum is very unique, in that we are VERY heavy email users..... much more so than most. This is a function of the history of Orchid (it had always been administered exclusively over email until I got it) and also a function of our users many of whom prefer the email format.
A few heavy users like us were up in arms about it, and the the good news is, because the software is open source, we can write a "plugin" to do anything we want assuming we have the time, expertise, and money to do so.
It's already done we finished it last week . I think it may actually be live now (@leah-ganoksin-admin can jump in and say, as she is the brains behind that operation)
I would say it's a medium task. It probably cost us around $1,200 USD to add back the functionality. Not expensive in the scheme of custom software, but quite expensive in the context of Orchid.
