The subject of the title here is Edit By Way Of Post. Since you can't actually edit your posts, legally, you would need to reply to your own post, putting this in the title to change something you've said.

Or, as in my case now, it can be used to be an addition to something you've said.

My addition is thus: We could start with a number of things but I've only thrown out one. But I know there's more you guys can think of so I'm not too worried about it.
