I have seen a lot of studs listed as 'private' in their stud rules/description, sadly many of the times a stud is private I miss it and send the request before I realize he actually is private! I have a quick idea that may help clear up any problems private studders may have!~

Adding a "Private" or "Exclusive" setting for your stud! Much like the method used for appointing new admins in a clan, you can open studdings to specific players or even a specific clan of your choosing(there can be two text boxes for you to do this) This way, only the people who you are open to studding will have access! This list would not be public, for your privacy it would only be visible for you!

Another idea is having a 'no stud' list.. this one would be more for those who are open to studding but do not want certain people to stud to their king. This could work in correlation would the above idea, or it could be a thing entirely on its own! Of course this list too would be entirely private and only visible to the user! This is mainly a sub-idea and would be more of an add-on than anything else XD

I am always open to ideas and constructive criticism on this so I can fix it and make it more to everyone's liking! ^^
