Welcome unstoppixe i am also in the same position as you. i join phpfreaks a while now but am so busy learning everything else becomes trivial. Am learning php\ mysql, javascript, CSS, perl and web design at the same time yeah am mad!! good luck with learning as well!!

A website should be aesthetically pleasing- IMHO your site don't possess much of that quality. my simple phrase : "the quality of the site determines the quality of the site content". The idea of the site layout is good but you're not utilizing the space you have correctly. especially the elements on the page showing a single tutorial, are not structured properly, looking like if they struggling to breathe. you may consider to : tweak the layout color: use a color scheme or use a color to complement the green. This is just my opinion.

the design is good but the colors are off. find a color to complement one shade of green.

i second 1UP. the user interface should be revamp.(colors and layout.The elements on the page is choke up).As the developer you may think that the website is perfect but your users will discover mistakes that might be overlooked by you. Let users be your eyes.i Don't want to be blunt here but i spend under 2 mins on the site because the site usability is poor. Have a look at dont make me think steve krug book, based on usability. 5 /10

hey does anyone know how to build a live streaming application: well the purpose of the application to allow music tutor to teach piano lessons online live and accept payments directly (maybe through pay pal). could anyone discuss what technologies i must have to develop this application please.i will appreciate the help

could anyone with the experience discuss how to approach/plan developing web applications from start to finish. i know there are methodolgies to follow in developing applications but i want everybody opinion well who could answer.

Web development books (PHP & mysql): Beginners: )PHP for the Web: Visual QuickStart Guide (4th Edition: nice job done by author Larry ullman bottles up everything for php beginners ready to jump into the web development world. PHP 6 and MySQL 5 for Dynamic Web Sites: Visual QuickPro Guide (3rd Edition): another good beginner book. the book takes "little" faster pace in the process of teaching the concepts to the reader but still full fills it desired purpose remarkably. PHP 5 Advanced: Visual QuickPro Guide (2nd Edition):after you covering the basic and having practically a good grasp of PHP and MYSQL this book will expands your horizon by teaching complex concepts of using PHP and MYSQL to its fullest potential.

i second what fugix said instead of killing him more u should lend a hand shortysbest thats whats the forums for. share some of your knowledge to help him achieve what u have achieved.

yeah currently am learning php and MySQL using PHP for the web by Larry Ullman,a good book. practically i know the basics already i decide to revise them so i can have a good foundation of the basics then build on that. then again sometimes i'll feel to run ahead and skip chapters of the to build the sample application it provides.lolz guess am impatience.

simple but yet effective. i will rate it 20/10 *simple layout design *ease of navigation *nice color scheme but could improve (add a complementary color to blend with the blue and white)

don't mean to be blunt but your website need a total revamp. You totally wont draw the crowd but instantly run them. you need to review the principles of web design eg. Layout, typography, easy navigation,usability etc.guess this is your first try so try again you can do it.

YEAH i am passionate about web development .i have tons of books and resources on it but just dunno where to start lolz .thanks for the opinion guys.so much to learn but will get there someday!
