I made a thread for replies like this.
Don’t hijack threads by replying to off-topic replies.

How to Reply as a linked Topic
Click Reply, in the upper left corner of the reply window is the reply type button, looks like a curving arrow point to the right.
Choose Reply as linked topic and it starts a new thread. As an example, you can choose GD, IMHO or The Pit for it.
That is actually the best method.
