Opt-In
The first step in preparing for a Guild War is to OPT-IN. This may be done by anyone in the top 3 ranks of Guild Leadership. Access the check-box from the Guild Wars Menu by selecting “My Guild’s Keep” followed by the “Admin” button.
This must be done 3 days before a Guild War begins, else the option will be locked. This is to give Guilds enough time to prepare their defenses.
All Guilds who have had an active member in the last 3 months will be automatically opted-in to Guild Wars, but may disable that if wish.
