as part of getting to know the Fedora infrastructure, I noted
EmailAliases - Fedora Project Wiki, which tells me
In order to get your email aliases, you must create an account in the Fedora Account System . You must also sign the Fedora Project Contributor Agreement and make sure you are also approved in at least one group as well.
So, in my reading my account should be eligible for an alias. But none is created, though the requirements are met, I believe for definitively several days.
I wonder whether my reading of the wiki is wrong, or if something does not quite work as it supposedly should, or the description on the wiki is not up to date.
