I have heard how giving you are in so many respects of music schooling and I must say that I am impressed. You remind me of the pure idealism that we had in starting Apple. If I were young, with time, I'd likely offer to join and help you in your endeavours. Keep making people happy, not just in their own learning, but in the example you set for them. 
On a day when there's a temptation to go into a dark place, and only see all the bad stuff there is in the world ... greed, cruelty, exploitation, selfishness ... I get days like that pretty often .... it's great to find someone giving out, and giving out good, and operating on an honour basis ... There are so many people who can't afford Guitar lessons .... well, here's a wonderful guy who has set up a whole system of teaching guitar ... Blues, Jazz, Rock, even Songwriting, from the basics, tuning the guitar, etc ... upwards ... If you use his site, it's up to you to determine how much you can contribute ... but this is an amazing site .... he is also very aware of issues in the world which need attention ... a great channel .. Check him out. He's a giver.

String$:  When you're done playing, wipe your strings with a cotton cloth or old T-shirt that's been treated with a small amount of light household oil such as WD-40. This cleans the strings and displaces moisture that can shorten string life. This simple process will extend string life 3 to 4 times compared to untreated strings, saving you money, and giving you more time to spend playing your guitar instead of changing strings.

If you are practicing regularly, like you should be (at least once a day) be sure to change your guitar strings once a month. You will be amazed at how much of a difference in sound quality a fresh pack of strings will make. You don’t need super expensive strings. When I was starting out, I got by quite happily on my local music store’s house brand of strings that cost about $4 a pack.

Okay, so if the diagram had O’s across the whole thing, then you wouldn’t even have to touch the fretboard at all, you would just strum it. However, this diagram has a couple of other marks on it, and those indicate where we need to place our fingers. In this case, they are on the 2nd fret of the 4th and 5th strings. The frets are the metal parts running perpendicular to your fretboard; they are what the string makes contact with when you press your fingers down. On the diagram, the frets are the horizontal lines. So count up to the second fret, and put your fingers down just behind the fret, like in the diagram.
