SFWA asked me to serve on their new self-publishing committee and is positioning itself to allow indie authors entrance to the organization. I'm working out qualification criteria with the others in the committee, and we're also trying to put together a list of services that would interest indie authors. If you've got some ideas on what would make you join a professional organization, come leave me a note?

And please, pass that URL around. The more feedback I get, the more I can take back to the committee.
