Just thought I'd throw this out here, not sure if it's been addressed before as I have just gotten back from a hiatus.

A thing that bothers me (and quite a few other players I'm sure) is that there is no option to set an account that can have free studding. This applies for people who have a side account with a king that they want to/stud to regularly, but struggle with having to transfer fees across for studding between their main and side, and also there are only a certain amount of stud slots per week, which limits the number of times they can be bred to. Also a problem for people who publicly stud to people with both their main and side. I know traditional breeding exists, but it can be unpractical for people like me who doesn't have many territory slots on their side (and can't afford to expand it extensively).

Another feature could be implemented where the studding will go through automatically to the other stud, as I know people freeze their side accounts for various reasons (hybrid breeding, ect) and having to roll their account to access their side studs is just not always viable.

The easiest way I can think to implement this is to have this feature only available to linked account. Similar to the way players can switch from accounts with the button underneath the chat box.

EDIT: As suggested below, instead of having an infinite amount of private studding slots, having a limited amount would be better
