Antville's standard templates allows a creator of a story to make the story "also editable for ...". I take it that the creator of a story can always edit a story.

But let's assume I want to disable editing of stories altogether. Is there a setting in Antville which would allow this (and it's just not shown in the default select list), or is this impossible? If it's impossible - would it be possible to add such a feature in the future?

Related question: Let's assume I want to enable editing of stories in principle, but let users choose whether they want individual stories editable at all - when I post a story, I can decide to make it completely un-editable, even by myself. Possible?

I know it sounds weird to be able to block even yourself from editing your stories, but there's some use for such weirdness :-)

yes, the creator can always edit her own stories and comments. you can have the features you mentioned, all you have to do is implement them :-)
