Hey Folks, newbie here trying out Discourse on the [discourse.org](http://discourse.org) hosted platform.

When replying as linked topic is it possible to set the default ‘Select a category’ dropdown to the current category and limit the options to current and children?

Or at least force the user to choose a category before they save the new topic? I have unchecked ‘allow uncategorized topics’, but it still allows me to save an uncategorized topic.

Thanks all,

Chris
