As general guidelines consider these things as you comment on maps:
- Maps are made by the full spectrum of humanity. From very young, to uh hmm very 'old'. From native English speakers to can't speak a word of English. From experienced game players to casual and new as they come.
- Not every question requires a written answer. No response is sometimes the best answer.
- Shower encouragement and praise on the things you like, ignore what you dislike.
- Constructive criticism is perfectly fine.
- Meta comments (comments on other people's comments) can often spiral away from map discussions. Be cautious of topic drift.
- The above guidelines are not hard and fast rules, they are just guidelines designed to create a bias towards helping map makers make better maps.
