Okay.

Firstly you need to buy and address and some space. I actually followed a link from one of passionfords adds at the bottom.

25 squid for some space and a name and www.l33byt.co.uk is now mine!!!

The what you need to do is design a site.
Programs such as microsoft word/powerpoint will make you a basic site. Keep it simple and dont make it too complicated otherwise it will take ages to load.

If you are looking for something better Dreamweaver or Frontpage should be looked at.

Once your done save your work as a webpage. For a page to work the 1st page MUST be called index.htm

You then upload to your webspace via FTP. Basically a program which logs onto your space and transfers the files into it.

A quick run down.
