I am aware, Snog wrote this addon with just basic function in mind and so we have no extended privileg settings available. I would like to achieve, that admins and mods can opt to be excluded from this functions and the conversation shows the read mark checked for those usergroups only when they have answered. You know how users can jump the train when you haven´t answered promptly, but they saw the read mark 2 hours ago..
I would like to suggest such a feature for a future release. But until that day: could you provide me/us with a quick and dirty way to implement that via a template edit?
