It would be my suggestion that this blog site should have a search by author name option.  It's very frustrating when someone comments on your blog, and you click their name only to find their profile is private and therefore you cannot access their blog.  I find myself spending ages scrolling down through hundreds of posts, and nine times out of ten never find what I'm looking for.  Or is there a way I am unaware of?  Does anyone else find this an irritant?
