If you're looking where to sign up for the Venkon Army, please go here: Pending for Venkon Army.
A Pending Venkon is someone who's looking to serve the Venkons in the war and has been a Venkon Supporter before signing up to join. There is no time span in how long they stay in the supporter rank. If accepted, they will be moved up and acknowledged as a full Venkon, but it's still different than a Loop Venkon.
People waiting to have an answer back for their registration, the times may vary in acceptance/denial. It takes time.
A Pending Venkon may not just sign up after joining, it's required they take time as a supporter.
