Recetly, I have created another blog in wordpress.com.
Thought of changing the blog name. Struggled to find the option in the bunch of options available.
Goto Setting - --- General, you will get the text box to get the new name for your blog.
Reconfirm the name in the second text box. Thats why, you are ready to go.
Cheers,
