I bought a domain name and hosting at hostinginsiders, but I dont understand anything but html and I dont know how to create it....what do i do?

You probably wasted your money...first of all you dont need a domain name to put a site up....secondly, your internet service provider probably had space you didnt even know you had! Now go buy some cheap webpage software.....find something with drag and drop capabilities

Use an FTP program or contact Hotstinginsiders and see if they have a way for you to upload your webpages to their servers and you should be good to go. Be sure that all your links point to your new address that you bought and placed on their server. Say you bought "www.sexy.com" make sure when you make your webpages that your 2nd and 3rd "generation" webpages have links back to the main site or the link above them for easy access, then when you upload to the site, they should all work.

Why did you buy space and a domain name if you dont have a site created yet?

You need to learn HTML or have someone create a site or let someone use the space for you. I need some space.
