You will end up in your personal account area, which can also be reached by the alias "~your_user_id". Create a new directory (if it isn't already there), called "public_html". Change to that directory, and upload your files there. (Here are some instructions for uploading your pages using the various FTP programs.)
NOTE: If you are a secondary subscriber (an added e-mail to a primary account), you must ask the primary account owner to do the above for you.
Page file names must end in ".htm" or ".html". Link
references to these names must match exactly, including case, before uploading.
Case really matters, so watch for upper-/lower-case mis-matches. The server
will not find your files if they are different.
