awesome! maybe already on your list, but one thing that could do with tweaking is the email notifications - currently they're busy HTML messages with a huge banner image, rather than the previous text updates. Personally I find the new ones a bit harder to parse.
I had it forced so posts to "Support" were forced to be questions, however there is a issue with this on mobile - see https://github.com/NodeBB/nodebb-plugin-question-and-answer/issues/42
so have disabled forcing it currently until this is resolved.
The configuration change has fixed the caching issue that happened when people edited posts and others could not see the edits.
For those interested in what the problem was - see https://github.com/NodeBB/NodeBB/issues/5123
Forgot to update this - all the plugins are enabled again. I have been doing some work on the server today so there has been some moments of downtime. Currently everything seems to be running well, but I am keeping an eye.
