I have some problems using tags when in the blogs section. To see what I mean, click "Blogs" on top of this page, and then under "Popular Tags" select the Tag "Microstation" - I just get "Weblog not found"
Another issue with tags and blogs: When I go to one of my blog posts, there is a message to the right saying "No tags have been created or used yet" - what does this mean? I have created tags for my blog, this is maybe a different kind of tags...?
Kurt, I'm not seeing te same error when clicking on the Microstation tag. It should bring you to this page:

There is a small issue with tagging blogs that you may be experiencing. In some cases if you write a blog and fill in tags, these tags will not save. If you go back and add these tags you should see them under the blog post under "Filed under".
