two wordpress accounts

Hi.

I recently opened a blog using ww.wp.xz.cn Justhost hosting service. However, before this I also had a WordPress.com blog of the same name. Now that my WP.org blog is set up, should I delete my WP.com blog? I have changed the DNS address of the WP.com so both of them leads to the same site. But it’s confusing coz I can access my blog in 2 ways (through .com and .org) so I was planning on deleting my WP.com site. Is this okay? I bought my domain from WP.com so I’m afraid my new blog on WP.org would disappear as well. Help!
