This question already has an answer here:
This question is addressed to you, ♦ moderators. There is e.g. this question 10k+, which is full of very useful information. It's been a community wiki with more than 17k views with 51 answers.
The question is off-topic, there's nothing to discuss, but why it was deleted ? Couldn't you just lock it as you did with a several posts around ? The biggest problem is that our community can't even undelete it because it's protected by the ♦ law.
So now it's a community wiki question, which can't be seen nor even undeleted by the community.
Could you undelete that question and let the community decide what to do with it? And if that is possible, could you lock that question to keep its content visible and as it is?
P.S. those reopen votes are there because of curiosity. We shall keep that question closed.
