would I use a javascript script to redirect peoplke from one web page to another?....like they go to my old one and then after say 10-15 secs it automatically sends them to my new web site which is on a different host.

no use the meta tag below and put a link to your new site into the body of the page, just in case they don't get redirected they can use the link.

the link should say something like 'if you don't get redirected click here.'
