The Muse Online Writing Conference is the best online conference I've found, and it's free. It allows those who can't attend a conference physically to have a chance to learn more about writing, submitting, promotion, and other aspects we need to know.
Registration closes September 25, so people MUST register now: After that the forum link to register will disappear .
Also, the conferences has pitch sessions, where writers can pitch their manuscripts to agents and/or publishers. Check out the line up so far for workshops and pitch sessions, read the guidelines what and how to submit your pitches:
I hardily recommend this conference. 4RV Publishing will have a forum, and I'll be holding a workshop forum, too.
