the unwritten rules of bloggership

okay, I just started a 'blog on xanga and realized xanga ain't not very good (just like my grammar). i could use myspace but i don't want 13-year-olds posing as 16-year-olds to steal my ideas. and i think my toaster has a blogging function now. so anyhow... am i allowed to take my two posts from my xanga blog and put 'em here? do i have to delete my xanga content or can i have the same posts across two blogs?

oh dear, i've wasted my life.
