Thank you very much, Bruce, for taking the time to read and have bookmarked it for future reference. Did you see the site icon in your favorite icons or "favicon"? That is the usage of it which is to distinguish it from the rest of your favourites or bookmarks. :)
Yes, Roger. You need to have a personal domain for your niche site before you can do all these. Have you thought of one already? Think about your passions and select what you like most. Hope this helps! :)
