The return of Dungeon Fighter Online (OPEN BETA PT. I STARTS MARCH 24TH!).

But then how will we know which thread to read?

Assuming you're interested in whatever anyone has to say about anything in DFO, you read all the threads in the subforum. And you respond in each to its topic.
Multiple threads, properly titled, will help you if you later want to see what people had to say about specific topics. For example, builds for a certain class, the issue with missing Alpha characters, the whereabouts of Team Rocket, and so on.
