The only requirement for a chapter is that you have 3 members who are current IBC members. How often you meet is totally up to you. Some clubs conduct all their business online. Just be sure whoever you designate as the email contact is active so that Jack can get a hold of you to let you know when the IBC gets a new member who is near your chapter.
You can still do plenty of stuff only meeting a couple times a year. You can do a group aquabid buy and save on shipping fees by having the fish go to one member then meeting up to share the fish. Or just sharing your own fry, or meeting at a larger aquarium society's meeting to see if there are more betta people around to join you. And you can also make plans to visit IBC shows in your area, although I think the CT chapter is the only one currently holding shows. You've got the Pennsylvania club that just formed nearby too, maybe you can hook up with them for some betta fun.
