SmugMug sponsors a great forum for fellow SmugMuggers and photo lovers called Digital Grin. You'll need to register there, but it's quick and free.
It's not your ordinary forum! There are organized photo challenges, good humor, and great knowledge from people who've been there and done that.
It's the perfect place to ask your questions about lighting, posing, gear, composition, and more. You can also get feedback on your own shots from fellow photographers.
See you there!
