Hello. Our client is demanding functionality that a topic can be attached to more than one category. And then this topic should be repeatedly visible in all different categories pages that it is attached to.
I saw a big discussion here about this issue and I understand that this feature is not a part of Discourse forum and there are no plans to add it. Also we have considered tags, but it is far from perfect.
So we are left with the only option - to write a multiple categories plugin ourselves. As I have no experience in Ruby it means we will need to hire Ruby developer.
Can you write your opinion what can be the scope of this project, how difficult is it? Approximately how many hours it can take to develop a simple multi categories plugin for discourse?
