Right here is a great place to start! You can find tutorials & classes, there's freebies to help you build your stash, there are challenges to do that are great for learning new tricks & the people here are very friendly & helpful. If you need to know anything at all, someone here will know & if no one does, they will help you figure it out!!
Take a look in the galleries to see the cool things you can do digitally that you cannot do the traditional way. I have perused ALOT of digital sites & this is BY FAR the best one out there!
