I'm in the same boat as you, so this is also my obligatory and "substantial" first post. This is a second sentence, as my first post requires several sentences.
I'm sure this newbie posting requirement is a function of previous security breaches, or something to that effect, so I honestly don't find it to be ridiculous. Inconvenient, yes. Annoying, sure. But it's understandable, I guess.
I wonder if this is substantial enough? I guess I could post a recipe for soup or something...
