Hello, first I apologize for my rather limited English. If I write this is to suggest ideas to improve your games, then I thank you in advance for the time to give my ideas.
1- A wall of information or newspaper that only the actors of the alliance can consult would be a good point for the communications in the alliance. Example: Let the role of each staff member (diplomat ...) leave the names of the alliances, peace pacts (no attack) or even make a defcon system.
2- The automatic moderation of the cat on certain words is appreciable for the public cats, but it would be more interesting to remove it from the alliance of the cats and to let us moderate as it seems to us.
3- The system of the trial period in an alliance is a brilliant idea, but it would be even better if one could choose the duration of that period, the possibility of withdrawing it in a certain time or even regulating the rights that are Withdrawn Test period.
