Large organizations that invite writiers of all skills to become members are extremely valuable. I've belonged to a number in the past in California . Here in Arizona I am a member of Professional Writers of Prescott, Phoenix Writers Club and Society of Southwestern Authors. None of these meet anywhere near me.  These organizations (I call them Umbrella Groups) are managed by a board; collect dues of members;  put out a monthly newsletter and have a program chairman who schedules speakers (professional writers/editors/publishers) for the groups' monthly or bi-monthly meetings..Workshops or critique groups–small numbers who gather in homes or library alcoves to read and assist each other in perfecting their essays, short stories, poetry, novel chapters, are where the real work gets done.  One such in Porterville, California to which I belonged for 20 years and led for about half that time is under no Umbrella Group. Members gather weekly in the home of one member.  No dues, no newsletters, no board of directors.  One faithful member has written and published about a dozen books.  She has read her chapters week after week in that workshop.

Think about it.  If your Umbrella Group does not encourage formation of small groups that can work together to perfect their own writing, try founding one yourself.  I'm glad to help with information on the organization of the five workshops I currently lead her in Sedona.  We are not under an Umbrella group nor do we have any of the  the organizational responsibilities required of such.  We get a lot of writing done..  .
