Pat,
All of the chapters todate are chip and token people. Many also collect cards. Attendence at club sponsored trade sessions was open to all convention attendees (all are members at least for the day). No one was excluded because they were or were not a chapter member. Chapter membership had no bearing on attending any trade session. All chapter meeting were also open to everyone as far as I know. After all, they are hoping to get new members. Permiting / encouraging attendance at meetings promotes that objective.
I also do not see any need for a separate trade session for cards. I like the combined room where a collector can trade any gaming collectible without having to pack up and go to a separate location. The chip people did not interfer with my trading cards, the slot people did not interfer with me trading chips, and the strikers did not interfer with me trading cards / chips. I do not see why there is a demand for a separate trade room / session. The room provided is large enough for us all.
