it will take maximum 48 hours to propagate.
you can check your name server from domaintools.com
There no advantage, you are just changing the host.
Thank you for your reply! It is quite useful.
After changed the host will:
1) Will my previous site’s content be lost? As right now it is still up based on wordpress.com’s ones. If not, what can I do to not let it lost because of nameserver change?
2) Will I be able to upload through my host to the site validly? And how, if I want to upload a custom wordpress theme?
For the question no. 2 .. Yes you can upload anything. To upload the theme you need to login into the dashboard and go to appearance/theme section to upload the theme. But before that you have to create the theme based on WordPress guideline following their naming rules and coding the template with their styles.
The theme was did by someone and it was dedicated to wordpress, so I guess I’m on the right track.
I couldn’t login to my wordpress.ORG dashboard because simply is that I couldn’t find the login page.
