Go ahead and resolve this as invalid, I just need some answers and I didn’t know where else to post these questions.

1. Why are some reports closed or hidden (when they are not a security issue)?
2. How important is to confirm that a bug exists in outdated versions?
3. Is there a way to “mark” a bug so you can find it in the future (other than watching it)?
4. Is it possible to change your username on the bug tracker?
5. How is the main post determined for duplicates? It’s usually the oldest one, but not always.
6. What’s the difference between “Invalid” and “Works as Intended”? I’ve seen them used pretty much interchangeably.
7. What is the “Done” resolution for? It doesn’t seem to actually be used.
8. What are the requirements and responsibilities of being a mod?
9. Is there any way to see who uploaded a screenshot?
10. What does the grey line between some listed duplicates mean?
11. Why do mods sometimes suggest that a player makes a new bug report? Wouldn’t be better to just update the current report?
12. Why do some bugs duplicate other duplicates? Shouldn’t they all link to the main report?
13. In what order are issues displayed in a search? Is there a way to specify a preferred order?
14. How do mods decide if an issue is intended? Is it just their opinion?
15. Is there a way for the reporter to remove a screenshot from their report?
16. There seems to be a bug that is causing me to not get some of the notification emails when a report I’m watching is changed. Does anyone know how to fix this?
17. Where does one report bugs that affect the bug tracker?
18. Where should I ask questions like this in the future?
