Does this mean my blog should look exactly the same as on wordpress.com? I am currently using the Delicacy theme (which I have greatly customized), and I see that wordpress.org has the Delicacy theme as well (it's very slightly different though, so that's why I ask)
That's our aim - we'll do our best to make it look exactly the same.
Also, does the Guided Transfer include the cost of hosting? Because I already purchased a one year hosting plan because I thought I could transfer everything myself....
The guided transfer does not include the cost of hosting, but if you signed up for hosting with one of our recommended hosts, we can use that account and you won't have to sign up for a new one.
