This does happen... I think it use to happen more, than it does now. The affiliate chapter does not have to accept the member... Most chapters’ vote, after a probationary period... and it does not affect the chapter regarding total. Even if they are at total, they can still bring in the member. The affiliating member, also, does not affect the chapter's quota at recruitment time.
