Becoming an Accredited Genealogist (AG) is not a "membership" but an earned credential. The process to achieve that credential is outlined on the ICAPGen website, but essentially involves successfully completing the rigorous application, written, and oral exams.
Only those who have successfully earned the AG credential are eligible for the AG discount for the fall conference. Hopefully you'll still be able to attend! :)
Gwen, you can definitiely mention your published article on your application for accreditation. Put it on the experience tables somewhere, probably in the "Other Items of Genealogical Interest" section. As for your four-generation pedigree, you can use a pedigree of your or someone else's ancestors. It doesn't have to be a pedigree you have never worked on before, but it does need to reflect your own research. It is OK if you already have a basic outline of the pedigree before you start verifying everything on it.
Hi Gwen saw you had been in the chat when I checked in late. People are here off and on, but there are also scheduled chats and you can find them on the schedule posted on the chat heading. I host two - one about Pennsylvania on Sunday at 9 pm eastern and a Paranormal chat Tuesdays at 10 pm eastern. Another interesting one is Gen Trek. Hope to see you in chat sometime.
