I think limiting newb posts is a bad idea for two reasons:

1. If I had to register then wait two weeks to post, I'd find another resource. When people are looking for answers, they need them today, not 2 weeks from today
2. Remember, some people may be demo'ing a BB (for personal or business use), software, or both. Our demo BES server had a 60 day window. Again, waiting two weeks to ask a question (based on that window) would send me to a different site

I don't like wading through lots of unnecessary posts, but I think it's a better alternative than discouraging participation on the site. And who knows, people that are newbs today may eventually bring some real expertise to the boards...
