In about 5 days from today, on January 17-18, the server will be wiped of all characters who didn't play since October.
If you have got any characters on your account that did not log in since October 31, and you are interested in preserving them, log in at least once. If you log in for several seconds, your character will not be deleted.
Note that deleting is automatic, done by IFSO, so I won't be able to preserve selected characters or accounts.
You will still be able to create new charactes if your existing ones get deleted. Inactive players don't get banned.
Remember that players who were online for less than 3-5 minutes get cleared regularly.
