If I have a wordpress.com blog and do some posts for it, then buy a domain - what happens to the post title permalinks? Do they remain 'blogtitle.wordpress.com/date/etc' or do they change to 'blogtitle.com/date/etc'?
I'm trying to do a new blog (private for now, so I'd rather not give the URL of it til it's public) but will probably want to buy a domain for it soon, but should I want to link internally to any posts I need to know about this. Thanks.
The blog I need help with is artbyvalerde.wordpress.com.
