Previously I had to manually create a blog for you (and apologies to those who had to wait for this!) -- now you can create your own blog!
Just click the Blogs tab, then click Create a Blog. You can choose the group for your blog (high tech, swaying, adoption, etc.), and you can also choose who can see your blog (everyone, members, or Gold only).
I have also added a "My Blog" link to quickly go to your blog once you've created one. Happy Blogging!!!
