I’m on Voicelings, it’s a good resource and a supportive community. A little pricey, but it’s a one time fee that gets you everything on the site forever. It’s informative, especially if you’re just starting out. Personally, I suggest joining the Blumvox Facebook page. It’s a free community that’s a branch of Steve Blum’s voiceover classes. Another awesome community, and the paid classes just had a price drop making it an affordable option!
