OH GOD, ROSIM! SCRAP FREESMFHOSTING BEFORE IT'S TOO LATE!
Seriously, use 000webhost if you want to maintain backups and have freedom backend providing you want to stick with something free. Requires a little more work to set-up but we're all programmers here, right?
However, getting on topic a little. I took a look around and it's looking good, I really love your content so far and the way you've structured it. Really nice job! Sadly I don't have time to do tutoring in full swing as I'm busy with work and I'm working on an Android app in my spare time. I might poke my head around to offer what I can though.
I will certainly send people your way should I find some aspiring programmers!
(Amen to coding your way around maths homework - I do that too sometimes...)
