Hi,
I searched around for a while trying to see if this could be done in Flarum, and could not find. So i guess this would be a feature request or maybe an idea for a extension. If this is possible already, please let me know!
I run a non profit organization that is supporting people and groups in arts, culture and civic society and i want to create a forum for our members. We want to have a specific feature: Users should be able to register their area of knowledge, so when other members ask questions/makes a post you get notified if the questions/post is about your area of knowledge. Lets say you know how to weld. When you register you enter welding as a area of knowledge, when another user is posting about welding, let's say they need something welded, you'll get a notification. A part from adding knowledge at signup users need to be able to tag their posts so that other users can get notified when their area of knowledge is needed.
