How can you join GSIG? You must be a member of AEJMC (graduate student dues are $50/year) to join GSIG. GSIG membership dues are just $7 per year, which is one of the lowest membership fees for any AEJMC Division or Interest Group.
If you are not a member of AEJMC, you can find the appropriate membership form by visiting the membership page. Make sure to indicate that you would like to join the Graduate Student Interest Group when filling out your membership form!
If you are already a member of AEJMC, you can join GSIG individually through the AEJMC sign up sheet.
