hey can sum1 pl tell me sum good sites which can allow me to create my own sites and also which allow me to place google adsense
Google's Blogger does that, but I wouldn't suggest a free domain. The best way is to buy a .com of your own.
If you are new to it all though blogger is a good chance to test it all out at no cost. But domains are cheap, so it wouldn't be a huge loss.
I think go for blogger and use free blogger template you will get template from freetemplates.blogspot.com i think that is sufficient
