If you are new and you want to create a site. You need a domain name and hosting space. I will tell in another post about domain names but now I am going to tell about hosting.
Host for post, new words for some peoples. It means that if you make post on a forum then they will give you hosting space. I also used this. You have to make minimum fix amount of post, you can make more then that.
The other benefit of doing this is that most of post for host forum are webmaster related so if you work on that forum you will learn lot of new things. Every webmaster post of webmaster related forums. So if all webmaster posting on webmaster related forums then why not get a hositng account too from them.
If you are not new then you should buy a hosting account at good hosting company. I have both types of account.

Yeah.. ! In earlier days, i too used Post-2-Host websites.
These type of hostings are good for beginners.

And moreover,
we gain a lot of knowledge by participating in Forums.

I am not beginner but I am still using it..

Its saves money.....
