My nation was deleted and then resurected.But now it is not a U.N. member.How can I get back in without getting deleted for using the same e-mail adress?
Only one nation in the UN at a time. You can be in the UN with different nations (or the same nation with a gap of non-membership) as long as they aren't both in at the same time. This is my second UN nation, for example, but it uses the same Email as the other. As long as you don't have a different nation in there currently, you can safely rejoin with your old nation.
Thanks now to go register.Again
