I always assumed that you had to use the "http://blogname.wordpress.com" format to get to my blog. I've now found that "www.blogname.wordpress.com" works just as well.
Is this normal, as I couldn't find anything on the suppport or features sites to tell me this? Might be something I should have known, but I didn't.
Oh, and please don't take it away, even if it shouldn't work. I was about to ask for 25,000 publicity leaflets to be shredded because "they have the wrong address" - until someone pointed out that the "www" link did work!
