How do I register an "idea", and what does it take to build a website in the size of and similar to facebook?

[Mark aka jack573]

To register an idea, you should get a patent on it. There are strict laws to getting patents though.

One that I know of, is that you have not told the idea in public. So refrain from telling anyone your idea until after you get the patent.

You should do a search for patents in your country and also patent laws. You may also want to get a patent in different countries, so no one can steal your idea after you get a patent in your country and produce the idea.

Hope that helps you out.

As to your other question. It takes a lot of resources, people and money to do something like that.

You would need to get a web site (not too hard), then probably a databse or similar technology. Then you are going to need to make programs or applications so that you can do all of the things you want the website to do. Then you will need to get people to make all of these things, and of course pay these people.

I think there is too much to describe in just an answer on here.

Good luck with it.
