Hi Dan
* Badges are easily turned off. Those are On by default because it is a forum platform, more than a mailing list.
* How notifications look is just a piece of HTML in the settings, can be tuned to the liking if needed.
The sophistication I was talking about when it comes to interacting with the community are:
* there are 4 levels of "intensity" of notifications that one can configure individually per topic, or per category, or per tag - from "silent" to "normal" to "watching" to "tracking"
* can reply both via email or via Discourse web interface - so covers both world; for example, I personally communicate much more productively over the web interface, while others prefer email
* all the knowledge is well organized in categories and with tags, as well as indexed and searchable with all the filters one could need
* interlinking between topics, aka building a wiki-style knowledge base
* summarization mode for long topic
* wiki messages (everyone can edit - or people with certain level of access can edit)
* Q&A with "Solution" checkbox for category(ies) of your choice, aka Support channel (aka Stack Overflow mode turned on for particular categories)
* plenty of self-regulated community features, i.e. people can "flag" spammy or rude messages (and those hide them once certain amount of flags
All this, in my experience, helps the community to thrive exponentially by having those bits of engagement, searchability, knowledge-base ability, self-regulation etc - without the need of too much moderation.
Well, of course I don't have an intention to pursue this idea - just sharing a suggestion. Organizing knowledge and keeping it up structured and up to date is nearly impossible in emails. With Discourse you could have everything in one place - from Cookbook to Q&A to Documentation to Wiki to internal developer discussion etc. So I'd suggest at least familiarizing yourself with the reading I shared above. I genuinely think it can make the community more public and discoverable, and easier to interact with.
Thanks,
Anton
