We've followed Raymond and Larry's leads and created a suggestion box. If you have a topic you'd like us to blog about, post a comment to the suggestion box. We're not guaranteeing we'll write about every suggestion, but we do guarantee we'll read every suggestion.
Please note: If you're looking for support for a problem you're having with Exchange right now, posting on the suggestion box is not the way to get an answer. Try looking here instead, or check out the many active Exchange newsgroups and mailing lists where you can get help from other Exchange administrators, developers, and MVPs.
