For those who missed it: This program was first proposed here; the first round took place here; and the changes to the competition for this round were discussed here.
Welcome to the second Mi Yodeya answerathon! If you're new here, welcome, and if this is your second round, make sure to stick around, as some of the rules have changed since last time.
The goal here is to answer as many unanswered (i.e., no non-negative answers nor accepted ones), open, non-negative questions as possible (with a cut-off that all eligible questions are at least 30 days old), and get your answers upvoted (i.e. at least a net +2; in other words, all answers netting a Revival badge for previously unanswered questions).
Among the changes this time, there will be two simultaneous programs going on. Both will begin on Monday, November 4, first day of Bahab.
Have fun!
Main Answerathon
Once the contest starts, you must post every day1 and get two upvotes within 24 hours of posting to remain in the contest.2 Once all but one person is knocked out, the contest is over!
What’s the prize for playing, you ask? Potentially, thousands of reputation points, from 20 points for every eligible answer, plus submissions to our preexisting Best Answer Contest.3
How do you play? All you have to do is find a question from this list4 and post an answer.5 The more questions you answer, the better your chances of staying in (and the better your chances of gaining rep). Note that, due to the change in definition of "unanswered" for this round, if someone posts an answer to an eligible question and gets downvoted, that question remains eligible for someone else to answer.
There will be an answer below titled "Main Answerathon." When you've posted a qualifying answer, edit that answer to include your name and one of your qualifying answers in the section with the current date. If such a section doesn't exist yet, add it yourself to the bottom of the post using ##[Current Date].
As mentioned above, you must answer daily and receive two upvotes within 24 hours of posting to remain in the competition. Last user standing wins!
Public Answerathon
Starting this round, we will have a Public Answerathon. What this means is that even if you're not in the Main Answerathon, you'll be able to submit answers to qualifying questions without having to worry about upvotes or posting every day. This will be less a competition and more a community project.
Anyone, whether in the Main Answerathon or not, who posts any answer on any qualifying question (as defined in the Main Answerathon section) should include just the link in the answer below entitled "Public Answerathon." I will do a sweep of this post once a week, B"N, and remove links to deleted answers; at the end of the competition, I'll remove links to downvoted answers as well. You can remove your own links if you want to, but it's not necessary.
Note that all prizes for playing in the Main Answerathon apply here as well!
When the Main Answerathon is over, the Public Answerathon will continue until the beginning of the first subsequent Shabbos. At that point we'll do a tally and see how many questions we've been able to sufficiently put to rest.
Terms and Conditions
1 "Day" starts and ends at midnight UTC.
2Friday and Shabbos count as one day; all answers posted on Friday get 48 hours as a result.
3What's the prize for winning? Uh, um, uh, bragging rights?
4Note that this list, being from SEDE, is only updated once a week, on Sundays. You might find questions there which are no longer valid, as well as questions which were not yet valid on Sunday which are currently valid. For a more limited subset of questions which is updated every fifteen minutes, try this search query. Also try this SEDE query, which will try to filter the eligible questions by what's interesting to you, based on your top answered tags.
5Self-answering is allowed, so long as the question is on this list.
