I'm glad there is a new section about this. I'm still trying to find out more, myself. I'm still a little confused about the difference between having only one domain that you're allowed, and having various websites. I thought if you only can use one domain name, then you are limited to only one website? Yet from the advice and answer here, that appears not so. In that case, must you make subsequent sub-domain names for other websites from your one domain name you use?
