In view of this recent meta-question, I wonder what was exactly the process when questions were migrated from other S.E. sites to this one when they concerned TeX or LaTeX. I unfortunately was not part of the original followers and committers of the TeX S.E. Sorry if this sounds naïve.
-a- Were the original askers informed about this migration?
-b- Were there creation of new users in TeX S.E. from the original askers' accounts so that they own the original question?
-c- if b) were the users notified?
-d- if b) Was there migration of their email notification preferences?
-e- What happened to the original questions on the original S.E. site? Closed? Deleted?
