1tess, sorry for multiple posts, just got tired of this problem. Thanks for giving proper names at last.
The thing (whatever it's called) is supposed to be blue with silvery letters (the red-lettered was an old one that lasted 2 days). My gravatar account shows the correct one. So, what's a blavatar then? Why so many -avatars if one account can have only one irrespective of how many blogs I have under one name? That is so confusing, especially since my account lets me access gravatars, but I'll have to start looking for where to find and change blavatar now.
Found it (thanks to mentioning Settings - General in some forum thread).
I suggest you put a comment-free topic in Support that would tell people once and for all about the difference between blavatars and gravatars and where to find them. ;-) Am I correct that I have one gravatar for all my blogs (for my single identity in all all of them) but can have separate blavatars for various blogs under one account/identity?
