I'm paying wordpress.com anually for my current blog. Once i move to .org will i be paying my new external host, plus wordpress.org, as well as wordpress.com? Or only the external host? Will I continue to pay for my wordpress.com upgrades like custom design, no ads and stuff which i have purchased so far on wordpress.com even after the guided transfer?
Should one have good knowledge on HTML, CSS and stuff to run a blog on .org? Because i don't know squat about coding.
