Sorry if this is the wrong section, but is there a way for me to go from a “Professional” setup to a “Blog” setup easily with WP.com? I paid for the “Personal” plan and am in the process of mapping my domain from GoDaddy, but I've only just started building my site. If I delete it then go to the blog format, will I have to buy a new plan and lose the plan I already bought along with the ability to map my domain?
