For my "regular" work, I need to continue using IE (AKA the Spawn of Satan), so when I first signed up with WA, I did so using it.  Since then, I've been trying to create a first post for this blog and have continuously been getting an error which Stingray777 accurately described:

When I click on "create a new blog post", I get a "please wait" box which just goes on forever. If I try to type something in the Blog Title box and click save, I get the following error: Server failure. Please copy and save your work somewhere and try again later

As he discovered, the solution is Firefox.  I moved all of my favorites into bookmarks and hey, presto!  It works!

 Onward and upward!
