Whether a one day session, one week conference, or a month-long workshop, writing related events are a good way of communing with other writers, networking, and getting your name out there. In some instances you can meet and mingle with editors and agents. Some offer critiques or pitching sessions. Nowhere will you find a higher concentration of introverts enjoying each other’s company.
If you are looking for a critique group or want to form one, a local conference is a good place to meet potential groups or members.
Some are free. Some require a fee.
