I'm one of the admins of https://monitoring-portal.org which provides a platform for various monitoring tools and integrations. We're currently looking into making it more easy for users to just post their questions. The forum has more of a support character and not necessarily long discussions. It is a "come and go" with certain community members always helping others.
One of the ideas was to have a dashboard and forum button or form to post the question without navigating into the forum's sub tree. I've seen that in Discourse and I would really love to see it in Woltlab Forum.
Probably a form overlay would collide with the current layout, but a button and a new page with a form with a sub forum dropdown could do the trick as well. Similar to how you navigate into a Forum an click "New Thread".
Thanks in advance
