I'm a newbie who wants to learn how to use Drupal.
I have one DreamHost account and plans for 4 sites with separate domain names, all under the one DH account. The sites are unrelated in topic. I expect low traffic and don't care about speed.
I just set up a database and installed Drupal, successfully, but within just one of these sites. I did not use the multisite install, which seemed more difficult.
After I learn how to use Drupal on the one site, is it appropriate to install separate instances of Drupal for each of the other sites? Or is it smarter to delete the installed Drupal and start over with a single multisite install? If I should have used the multisite install, will I be able to change Drupal out later after I have added content? Or should I delete it right now and start over?
