New Gaming Portal: 4 Questions

I will be launching a huge gaming education/content portal soon and I want to offer
several options to online browsers.
Therefore, I have 4 questions:

1) I would like to tap into a feed for the latest gaming news worldwide.
Is there a recommended (hopefully free) service? I know very little about RSS feed,
so talk to me like I’m a 6 year old about what my options might be.

2) I would like to announce any new online casino games.
Where do I find this info? OR does someone here track this info?

3) What’s the usual disclaimer today for online gamblers, especially in the US?
This is an information site only and I am not associated/affiliated with any online casino.

4) Are there procedures still in place to educate newbie online players about starting an
online account?
In the good old days, you could provide information on methods of payments, set up, etc
at several online casino sites.

You can PM, email me or answer here. I thank you for your assistance in advance.
We will be offering ad space at this portal, but more about that later.
