So now I'm officially a newbie!
I hope I'm not being immodest but I don't exactly consider myself a newbie, not any more. On the other hand I've been "Just joined" for three years, which is even odder. When I was growing up, "just" meant "very recently" and 2004 isn't very recent in my book.
The problem is your wizards don't allow for intermittent visitors. When I started out with Linux, I didn't even have a home internet connection. Frankly I couldn't afford one (US readers please note: we have to pay even for local calls in the UK). I used to go online once a week at the local public library and I only visited the forum when I really needed to make a post. Then my pension came in and I began to feel affluent so I got a dial-up connection. But because it was metered, I used it mainly to browse for information. So I posted more often but still only once a week or so. I didn't start racking up the posts till I got broadband.
I'm not quarrelling with grading people by the number of posts they've made. It's obviously the fairest way to do it. But couldn't you find some names that don't assume an automatic match with the amount of Linux experience?
