I think he isn't. As he can't even correctly explain his problem. He can't seem to put together a well formed paragraph to explain exactly what happened. Yes, he might be frustrated, yes he might be new but one needs to think logically when trying to communicate with others. I don't even understand him. I've tried to logically go through his posts to help though reconstructing his problem seems very flawed.
The reason I say he isn't using the internet is because he hasn't given us any direction of his problem as to what others are saying on the problem either beyond that of this website. This website should NOT be his first stop to gather information on his problem.
His first stops need to be a simple Google search, Apple's Support page on their website, or Yahoo Mail Support page or even just restoring the computer as you should always back up before making any major changes.
Stop being a droid, be logical, don't be afraid to educate yourself, don't be afraid to fail, learn to communicate as together we are better.
Also, if he is so worried about making sure he can just have access to his Yahoo mail, why not learn about the software provided? Apple provides a Mail client. After getting his so needed email, he can then worry about his Safari problem because he still has access to FireFox and the amazing ability to search the web.
Wow! A Google search has given an awesome site that I can use to educate myself!

Educate first. If you can't solve, then ask logically by referencing the information you have used to educate yourself so others may understand the problem.
Communication is key. Yes, MacRumors is the Internet. Just not the first place you turn to.
