On the main site, in the questions section, I notice a lot of things. Here's a list of things you should do when answering.
1. ANSWER THE QUESTION! If you don't know the answer, don't even attempt. I was looking at one question, and the answer was "Sorry, but I dont know how."
2. Please don't answer old questions to get more submissions. I went to later pages, and notice questions from 4 months ago being answered now.
3. In Pokemon, when someone asks you to rate teams, don't just say "7/10". Give some reason as to why as well.
4. If you see a good submission around, verify it. If it's wrong, Bogus it. Also rate em.
That's all for now. I'll add more things if needed
