A good resource for quality javascripts is The Javascript Source . Finding a good web host is critical. You want someone who will give you enough space for the work that you are doing, give you the resources you need to get your site on the web, and also someone who won't inhibit your web designing. There are hundreds of free hosts, if you are not in the market for buying your own domain and space. It has been my personal opinion to stray away from hosts who force you to place an advertising banner on your page.
Homestead is an example of that.
Envy.nu may be the place for you. If you like FTP and don't mind a pop-up banner, Tripod is a good choice. Whatever your wants and needs, remember that simplicity is the best. In reality, your page probably will not take up more than 20megs of space. Night Games hosts all its files on Tripod and we still have 31.5mb remaining.
