Sentences interpretation; Facebook and its aftermaths

At their inception social networking sites were largely the province of the computer savvy young.

If you have an online bank account, your executors will be able to close it down and claim the money on behalf of your estate.

A virtual space station has been sold for $330,000 on a game called Project Entropia - though whether that kind of asset could be passed on would depend on the game's terms and conditions.

And how do we ensure that the people we want to inherit them, our loved ones, actually do?

I have some troubles understanding those sentences above!

I need a thorough interpretation for each one of them!

I think you want 3 sentences and the questions answered.

1) The word inception means to start or begin and province is something that a person knows about. If you were to reword this sentence it would mean that young computer savvy individuals were interested in or involved with social networking sites when they first started. This makes sense when you think about it, because many social networking sites first started with younger users.

2) Let's start with giving you some background. When a person has an estate or property (or assets) they may have an executor over their will if something happens to them. When you look at this sentence, it is saying that if a person has a bank account and dies, this executor can close that bank account and claim the money in the bank account on behalf of this estate. The executor carries this out for the deceased individual.

3) I think this sentence is a continuation or related to the estate sentence. The Game Entropia sold a virtual space station so it would be considered an asset by the person who brought it. Yet, this sentence is saying that you have to look at the game's term and conditions to see if this virtual space station can be inherited. An easier way of understand this is: If someone plays a game and buys something in that game, can someone claim it after that person dies. It is almost similar to question 2.

4) I'm unsure if you want me to explain this question. It is asking what can a person can do to make sure their loved ones receive an inheritance. This could be belongings, property, or any other items.
