I posted a question on a boat forum like ten years ago and forgot about it.
I got an email notification. Almost thought it was spam.
I went to the post from the link in the email and the reply the notification was for was the only one.
I looked up my password, logged in and replied as if I had posted the original question ten minutes ago and it ignited a conversation that ended up 3 pages long within a few hours, and not a single person mentioned the ten year gap between the first and 2nd post.
