I seem to remember that there were a couple of 'beginner' threads to point new players in the right direction. Some websites might have been taken down or may not be free. If you have your uke tuned up then you can look for forum member Uncle Rod's ukulele bootcamp: http://ukulelebootcamp.weebly.com/
ChoirGuy a member here on the Forum has a blog: http://ukestuff.info and play along videos and uke reviews.
Another excellent resource is https://www.gotaukulele.com/ by Barry Maz in the UK. He has tips, information and ukulele reviews. Particularly for beginners as well as more experienced players.
