Welcome to the Q&A Forum

I recently created a forum for my website (lets say my site is xyz.com so my forum is forum.xyz.com) and I've been getting status code 200s for tons of my forum pages about duplicate content- especially for threads that have a ton of interaction. Is there a way to fix this? I want my forum to be indexed and not get penalized, but if i canonical tag my main forum page wouldn't that take away the glory the awesome interactions my users are having? Anyone with forum experience can shed some light on this? Thank you so much!
