BBS SEND OPTION

I have never used the “send” option, it is curious because I want to know how it is used and what it is specifically for. Is it used to send buyer balance? . I once suggested something like this in an old post but I don't remember researching that option before. I suggested that it would be nice to be able to transfer the money to other BBS accounts if we wanted to. For example, if a friend or user with whom we recently interacted needs a purchase balance, we could transfer them while they recover.
