These forums are set up to encourage you to keep posting.
You've noticed that posting X number of topics and replies changes your title, this is no different. Most title changes are made to make you feel good, some (several) aren't and I guess the idea is that when one of these titles gets hung around your neck, you'll have figured out the drill to post more and change the title to something better.

Why is it done like this? No idea, I don't work here.

It might be that submariners need to take themselves seriously, but not TOO seriously?

Either way, keep posting and it will change again.
