Dilemma

So, it occurs to me that the title of my blog annoys me nowadays, no longer being as pertinent (as I presume the number of obsessions I have will continue to grow - I think now I'm up to four or five things that could legitimately be called obsessions, which is still less than the number of obsessions racked up by, say, my sister, my mother, or most of my other siblings, who all seem inclined to hyperactive obsessing, but whatever), and it's also not sufficiently descriptive or witty to suit my tastes. I assisted with naming my husband's blog - the name of his blog amuses me, and now I feel dissatisfied with the name of my own. However, the title of the blog is tied to the web address . . . I wonder if I can still change things (i.e., both title and web-address) without creating an entirely new blog (thereby keeping all my post history, tags, etc.) Does anyone know?
