If you finished your pages and are ready to put them online, your next step is to get yourself a host. If you're using your own domain, you'll probably need a paid host such as PowWeb, Canaca, etc. You will need to set up their domain servers (ns1.webhost.com, ns2.webhost.com.. replace webhost.com with whatever your host would specify) within your domain's regristrar (where you got the domain from) account panel.
Once you've finished with those, you'd need to use either the host's file manager program or you would need an FTP client. FTP (File Transfer Protocol) is the easiest method to transfer files to the server because you can view a split screen between your computer's files and the server's files. There are plenty of instructions for FTP on the internet. For me to write them, it would take up about 10 pages... and that's just for the basics.
In your new user root directory, you would need to upload your files and folders. Now the way this works, at least for the basics, is that you should have an index file as your entry page. It needs to be named index.htm or index.html and this is the file that would allow users to access your website directly if they were to type in www.yourdomain.com/ rather than www.yourdomain.com/index.html
Make sure all of your pages are properly named to match the links on each of your pages and also make sure the links themselves are referenced correctly and don't include your own computer's file paths such as C://Documents and Settings/My Webs/My New Site/Me
There are thousands of places on the internet where you can find html tutorials. A good start is at http://www.htmlgoodies.com/
My advice is that even though you may have a wysiwyg (what you see is what you get) editor, you should at least learn the basics of html because you'll find yourself tweaking the codes quite often.
