I'd like to give my blog its own domain, but have two questions.
1) I'd like to ask though if I can do that with a new username, but keep all the old posts.
2) If I leave it on wordpress servers, what sort of access do I get to it. Is it via FTP? Do I get access to ALL files, just as if it were on a third-party hosting space? I'm not technically advanced btw, so apologies if that's a weird question.
The blog I need help with is cijblog.wordpress.com.
