First off, considering this is my first post, I have to say: awesome software. I love NodeBB - it's fast, has great features and looks pretty. What more could you want?
Could you perhaps turn this into a language-based string? Or, even better, make the message editable from the ACP?
For now I'll just edit the text directly in the html.
It's good for seeing all past notifications, but it could be extended in the future to include "notable topics" maybe stickies or "promoted topics", things like that. I'm not sure how many the drop down shows at any one time, so if you're mr popular, you might miss a few because it only shows the last 10 for example.
Final update, it worked on the production server!! so now our forum is working properly sending emails the Linux way on a Windows Server OS, quite nice I would say, just as a side note our forum is actually really small in number of users, as it is an internal forum, so I can't assure this setup will work out to other forum's expectations or needs, also I would like to add that this shouldn't be the way to do it on Windows as it is kind of a weird way to handle it so in later versions it would be nice to see it reworked or polished for Windows environments (especially because it looks like the program used to simulate sendmail on Windows is no longer receiving maintenance).
The second one could probably be achieved with 3rd party tools already. The best one I can think of would be IFTTT. Each category has an RSS feed, therefore if RSS feed gets updated. Send email. Full IFTTT support would be great, I'm not sure how that would work, but being able to set up that sort of thing would be bloody brilliant. Maybe even baked into nodebb, so we can set up "tasks" similar to how stamplay.com works. Just with a betteR UI.
