not muting, but suppressing the category from homepage:
e.g. we have a category named “invitation to edit”, and topics which needs some edit are pushed there. and we don’t want to show those topics in the latest topics until they get edited.
so we use this option in the category setting:
then if we set the category page as our homepage, those topics are shown in the latest.
but if we set the latest as our homepage, topics are not shown.
In fact it’s working as it’s saying, since in the first case our homepage is not the latest page.
but the only place you usually want to suppress a category is from the latest page; and not the category page itself.
