My nation has vanished!
First, make sure it really has vanished. When you search for or try to login a nation, you must enter its name (e.g. "Mynation"), not its full title (e.g. The Republic of Mynation).
If it's really gone, there are two possible reasons why. If you haven't logged it in for 28 days, it will have been automatically purged. Otherwise, a moderator may have removed it for breaching the site's rules.
You can submit a request for the moderators to restore your nation. You do not need to supply your password -- the name of the nation alone is sufficient. You will need that password to log in once the nation has been restored, though.
I added emphasis on the parts that are outdated and need to be updated. Perhaps adding something such as the following would be better.
"In olden days, you had to submit a request to have your nation restored. This is no longer the case. Now you may restore a nation by simply trying to log in to your old nation, and using the restore nation feature when prompted by entering the correct password used for that nation. It's that easy."
