I don't think anyone has a lower posting rate than me, when you calculate the number of posts versus the length of time I've registered as a member.
The only person I can blame for this situation is myself--many times I've thought about posting, but I am lazy plus others say what I'm thinking much better than I can write such things.
Therefore, I say we keep the ratings the way they are. Through my laziness I have 'earned' my newbie rating, and I should be known by it to all those gathered here.
However, perhaps everyone will join me in celebration when I finally graduate to the next level!
