Affiliate Marketing Secrets

I Love the USA but i do feel it has lost its way.
Basically the Wrong priorities. College is way too expensive,
it is very TOUGH to get a decently playing Job. Dollars are
Wasted on importing fuel from the Gulf Dictatorships.
Too many Cars. Not enough trains. No Freedom.
Taxes too High, Money wasted on corrupt government.
Now Al Qaeda affiliates getting Armed by the CIA in Syria.
Is it just me or do many feel something has gone seriously Wrong?

I have youtube channel. And every of my video has the following statement in the description:
This is for educational purposes ONLY. I am NOT registered/partnered/affiliated with any of the companies/products shown in this video. Try and support the developers.
I am in no way responsible for; anything caused to your computer, you getting in trouble and/or you resulting in any of several unforeseen consequences. Do this at your own risk. Thanks.
Can I put that statement under a Disclaimer heading? And what does disclaimer mean?
I have a channel where I upload tutorials on how to ‘download’ PC games… if you catch my drift…

Hello, I am writing a simple web site. I successfully made the register and log in pages, but now I want to allow only one session per username.
More detailed: When someone logs in a session starts.
If he tries to log in from somewhere else, I want the first session to drop before starting a new session.
How can I do that?
-I already thought of keeping the session ID in the database and change it when the user logs in from another computer. When he tries to go back to the first computer and clicks any link, it checks automatically if the session_id that it has is different compared to the one saved on the database. If it is, it automatically logs out. I could add timed sessions so if the user does not come back to his first computer it automatically closes the session etc.
Problem is that even if I do that, the server will be loaded with sessions that will never be used again until the sessions get timed out. Is there any way to close the session (lets say close a session by knowing its id)?
Any other ideas?

Okay, so I have the concept of advertising on twitter, which was the simple part, but how do you go about getting a decent user name?
Let’s say I was advertising for Nike, I wouldn’t just have a twitter account that said @nikerunning… That already exists… So how should I go about changing the name to something that works, selling what I’m selling, and not copying Nike?
(By the way, I’m not advertising Nike, just an example).
Anything helps!

I wrote a book earlier this year call ‘In a City Named Joy’ and it is available on Amazon.com. I wanted to know if this was a good summary or not. I would also appreciate it if you could suggest a way to improve it.
When Amy Harris, Morgan Anderson, and Brittany Edwards move to a small hill next to a city named Joy, they find that things may not be as normal as they expect. The women are shocked when the people in the city aren’t as nice as they would have considered for a city with such a name. Brittany stops a man from destroying a super market and Morgan tries to help a man cure his five year old sister. Amy seems to have just been taken along for the ride.In the middle of all of this a
scientist is trying to make himself famous by creating an invention to kill the people on death row.
When this is tried out on a young woman named Grace, who has an unusual habit of killing people with their worst fears, things go wrong. Amy, Morgan, and Brittany end up having to save the city with the help of two men that they met in the city and the Immortal who insists on helping even though Immortals tend to think highly of themselves because they can’t die.
