A few rule clarifications, one on the topic of user's groups of Avidae, and the other about AP:
Users do not need to have separate groups of Avidae! multiple users can collaborate to create groups of Avidae together, and a user's Avidae do not need to all be in the same group.
For example, user A and user B could create a group together. User A has all of their Avidae in the group, but user B has some of their Avidae in another group, and a lone Avidae as well. These groups can be original groups, warriors-esque clans, tribes, lion-like prides, or any other group formation you can think of.
Secondly, the AP you earn in an activity prompt (along with the EXP and items) is part of the activity rewards. The person who's Avidae is completing the activity submits it to the activity thread, and earns these rewards.
The AP you earn in the Shop is rewarded to the artist/writer of the piece. The person who completed the art/writing submits it to the shop and earns this AP. You can earn AP for both if you are the artist for your Avidae's activity prompt.
