Congratulations on getting approved. I will try to answer some of your questions. When you log into your Adsense Account, the first page that comes up is your home page and it shows how much you earned today, this month, total and any payments to you so far.
There is another button/link on the home page somewhere (left hand side? ) which says Account Details? And shows your account details in more detail, a bit like a bank statement, which is a good way to keep track of your account.
Google Analytics - I have never used it so can't help you there. Re Tax - Do you live outside the US? I live outside the US, in the UK, and am a Tax payer, so on the Tax Question I ticked the one that says I don't live in the US or have business in the US etc.If you live outside the US, I think this may be the best answer for you.
You may not be paying tax now, but you probably will be in the future and I think this is the answer for you. If you are a non-taxpayer because you are too young or a student, choose this because it won't affect you anyway. You won't have to submit tax returns.
If you are old enough to pay tax, but haven't got a job, you may still have to pay tax on your Adsense earnings. In the UK I have a Tax free allowance where I can earn upto £7000 before I pay Tax. The tax laws in your country may be different, so you will have to look into them.
Hubpages Ad Program - To join this you need to be approved by Google Adsense first. Now that you have been approved by Google, you should soon be able to join Hubpages Ad Program. For me, Hubpages sent me a message inviting me to join.
It came up when I signed into Hubpages. Keep signingin over the next few days, if no luck, go to the learning centre.
I have no idea about hubpages ad program. But for adsense, if you got clicked your earning will show in the home page when you login to adsense account. Further you can view the earnings for a week, month or all time.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
