Thanks for the compliments, but as for answering all the questions, I'd really prefer more user involvement ;) That would make it more of a community than a "get Dan's opinion" board.
One questrion more.. The example I wrote in my last post, would this be considered black hat? Is there any ways to cloak in a white hat-way, but still showing the main page to visitors, but a SEO page to the spiders?
It's definitely black hat. Cloaking for the purposes of displaying optimized content to spiders is always black hat, no matter what technique is used to do it.
