This great list of online resources curated by the folks at Pen & Paper Writing Workshops includes 9 sites I often frequent myself for places to submit, writing tips, prompts, etc. including my own blog! Special thanks to P&P for listing me among these other fine sites.

“Here’s a list of resources that we use on a regular basis. These websites have proven to help us in many of our writing endeavors. This is not, necessarily, a definitive list--there are hundreds of these types of resources available out there--but these are the ones that we follow, or read, or use the most.”
Pen & Paper Writing Workshops provides weekly writing tips and resources on their blog and a variety of online writing classes and one-on-one consultations for fiction, nonfiction, and screenplay writing at reasonable prices through their web site. “We're a community of writers at all levels here at Pen & Paper Writing Workshops. Our community is wholly important to us. Come, join us. Let us teach you. Learn from us. Learn with us. Most importantly--write with us!”
