Howls are short lines of text which can be submitted and read in Jammer Central. The first time you submit an approved howl, you will receive a jam-a-gram from AJHQ with a Howl Plaque if you are member, and just a gift like a code if you are non-member. The howl Plaques has a golden wolf howling at the moon on it.
How to send a Howl
You go to Jamaa Township, and you can see above Jammer Central, a message board, where you can send your howl, post art, watch a cool video, and check the activities calendar. Click on Jammer Central, and you can see the button that says "Submit A Howl". You click on it and you can type your howl to send.
