I would like to create a torrent site like Extra torrent or other torrent site,and if is possible how u get started?
and what sense u mean legal? and licensed?
God Created these sites, no mere human can make them. Its 100% impossible to make.
When the internet formed on the 7th day, torrent sites formed on the 8th.
If your a Blasphemer, you can try this link, which tells you maybe how to recreate some of the work
