{{{each topics.posters}}}Thanks again you save me here.. 🙂
@bbb cloning topics is messy business. Do the replies get copied? Do later replies get copied? I suggest using tags if you have a lot of overlapping categories.
That's a policy decision. I can see at least two practical solutions:
Copy only the original post, and let the topic have a life of its own.
Copy only a reference to the topic, so it's in effect a different view of the same topic, and replies to any views show up in all views.
Tags don't quite address the problem.
