"wiki-offline-reader-l" has been inactive for many years.
I think it is even impossible to register anymore.
It has been superseded by offline-l for years.
This mailing list has been currently, like the others, suffering of dozens of registration requests from @aol.com and @yahoo.com email addresses. This is spam.
I'm the only admin left and I do not remember my password.
I think it is the right moment to simply officially archive the mailing list and delete it from the Wikimedia mailing list board.
