That doesn’t seem to have annoyed the author of this theme (he liked my message).
May I suggest you to read these threads?

The general consensus is that it’s not a problem to reply to an old thread (as long the response is relevant to the original thread, which is the case here).

PS: btw, I don’t plan to copy-paste this message anywhere else.
