Welcome jaffrey! You do realize that GuitarTricks is strictly a guitar oriented teaching site and that there are no ukulele tutorials or music anywhere on this site, right? Hopefully you meant that you started with the ukulele and now want to also learn guitar.
To my knowledge, the only teaching site that includes ukulele tutorials is TrueFire.com. But even there, dedicated ukulele teaching resources are pretty meager. I know because I recently took up the uke and ventured out in search of teaching materials.
