Hello guys
I'm questioning the best way to make a website such as "orkut" or "Facebook", on which anyone can sign-up a free account, log-in and post some things like video clips, textual content or images.
- What type of application do you recommend to create such a website?
- What might be the simplest way to host this site
I know little about website-building, but I have never identified any program providing these features such as log-in zone + account, and so on.)
Thanks for your help
