As far as how often meetings are held, there are two different formats. Career chapters meet once a month and traditional chapters meet twice a month. Each chapter determines which format they want to follow.
My online chapter ranges from 21 (me) to sixty-somethings, maybe older. They've never really shared
I know that the age ranges can sometimes turn people away from Beta, but I think it's a great opportunity to learn about the sorority from someone who has been a member for decades.
Let us know if you have any other questions! I would love to hear what you decide/find out!
