Until June 9th please include all narrative spoilers in spoiler tags.
Following this we ask for common sense discretion (e.g. late game story beats tagged as a courtesy to other visitors who may not have finished).
When it comes to gameplay/mechanics use discretion and air on the side of caution but if there's any new items, slates etc that were not revealed pre-launch then use tags during that time too. If you can't remember it it was in the pre-launch material than please air on the side of caution and tag them as a spoiler.
I've "recommended" this post so now a preview of it should appear at the top of each page. It's a feature we've not used before but I played around with it a while ago.
