JAWS UG Nagoya is the one of 5 oldest AWS user groups that launched in Japan. Since then, JAWS UG was able to keep meetups going every month. However, it was not easy from the beginning.

Tip 1: Don't reply on a single leader. Try to distribute the workload as much as possible by assigning as many leaders as possible.
Tip 2: Every staff needs to opt-in to continue to be a staff in the following year, so that the UG member can keep up with a good motivation.
Tip 3: The after party is must-do for meetup to grow, get feedback, brainstorm next meetup topics and recruit staff.
