for the .tk, theres not much to install.... you go to the site, and sign up and everything.. then the .tk should lead to your site. www.yoursitename.tk
Thats basically it, log into tk site, and just edit your sit so that the .tk domain redirects to your acftual forum link, or domain.
You just tell everyone to go to the link with .tk into it, you don't edit anything on your actual site.
As mentioned above, .tk is a redirect, not nessesarily a domain. same thing as dyndns.org except .tk sucks cuz sometimes it will have ads.
Ya, it is simply a redirector... google only caches the front page of .tk and it caches the rest of your site in it's originaql location, there are a few free domains that you have to apply for but are still free...
when you buy most hosting, itll ask for a domain, which you pre-buy on go daddy...most sites ask for the domain which u supposedly already bougth
not if it's a locally hosted server on your own computer. Then you simply use dyndns.org (or in this case .tk) to shorten the url.
