Don,
Is the Join email sent before or after the transfer to 开云体育?
If you mean your group's Welcome notice, that (if you set one up) and the system-generated welcome notice are sent to each copied member after the copy of membership and content is complete.
Originally those had been sent when the membership was copied, but that sometimes prompted eager members to post while the copy of the messages was still in progress, causing the messages to be intermingled. So now the welcome notice is deferred until all content is complete.
