umm, yup, i'll agree on the "two left hands" comment
they mean go to your site, in this case, the site you made here on freehostia.
just so you aren't waiting for me or someone else to help next...
if you haven't got a database set up, do it now, before anything else, and have the database info handy, you'll need it in step 4, and after that, you'll basically be ready to go.
you'll need this db info:
user name
password
db name
db host
you get all that info in the email sent when you set up the database
user and db name will be the same
password: in the email
db host will be something like mysql3.freehostia.com
good luck!
