I assume that I am somehow automatically watching any topic I create or reply to, unless I click the unsubscribe star. I am guessing that being subscribed means I will get some form of notification if there is a reply. At this point I have no idea what form it will take, but assume it will be either on a watchlist or by the notices and alerts icons at the top of every page.
If I hide the topic, does it become permanently invisible ( I would not expect this) or can I restore visibility. I will now test this.
It seems that I can undo a hide. Makes sense.
Who can hide a topic? Obviously I can hide a topic I created, but can someone else hide my topic? I assume that admins can.
