I stumbled on a website a couple days ago that I think is worth checking out if you are interested in improving you photography skills. It's www.digital-photography-school.com/blog
On this website you will find a forum with subjects like
critique my pic
How I took it
There is a tips section which covers subjects on:
tips for beginners
cameras and gear
There are also sections that have information if you are thinking of upgrading your camera or want to make money from your photos.
I haven't gone through the entire website but I've seen enough that I thought it was worth sharing with you.
