Hi, i've been browsing the forum and thought I should say hello. I don't have a ukulele yet (soon to be rectified), but i've been playing guitar on and off for a couple of years.
Welcome to the forum. The chords are a little different from a guitar unless you use a baritone ukulele, but the principles of strumming and fingerpicking are similar, so you have a good jump on easily playing a ukulele.
