Fantastic! This blog is a collborative effort of incredibly useful information. I love the explanations of the tools and techniiques used to lookat problems and the detail of the technologies involved. I watch the blog daily - I just wish the other server product teams would take a leaf out of your book and get their own blogs, with content preferably modelled on what you provide.
I would like to see more articles aimed at SMEs. All of the exchange documentation seems to be aimed at building large farms handling huge amounts of email - SMEs, with tight budgets and the same demands as large enterprises albeit on a smaller scale, often have to find innovative ways of shoehorning the capabilities of 3 servers into one. I am the sole admin for our company and Exchange is only one small part of my job. Thanks to this blog though, it's made it one of the easier parts.
