I use webhosting through yahoo and got a wordpress blog to go with it. I've done two blogs.. basically my intro blog and one about must have office equipment. Last night I go into my blog to type another one.. (I'm trying for at least one every two days).. and BAM.. it asks me for a username and password.. I don't remember making one

So I click to recover my password thinking maybe that will job my memory on my username... and it asks me for my username to retrieve my password...

So now.. I can't blog because I can't find a place to retrieve my username

Can anyone help me with this??
Thanks,
Shannon
