I set up an account at BlueHost and my unfinished site is now live at columbiablooms.org.
My understanding is that when I make modifications, such as enhancements, that changes are made not only to the file structure, but also the database meaning that from this point forward I need to make all my changes and content additions to this live site. Also, I want to be very careful to backup both the file structure and the database before I make changes in case I mess things up.
At this point my Acquia Dev Desktop is not very useful since there appears to be no way to merge what I've done on my local machine with what's live out there on the web.
