I understand your protest, I understand why it’s being done. However, over the past few days there have been several times where I have searched for a very specific warframe related question, only for the answer to be on reddit. The sub being private makes it entirely impossible for the scores of warframe players looking for answers to access the well of knowledge we (warframe redditors) have compiled over the years. So, if the sub (permanently or just for the time being) is not coming back, I ask that the moderators at least make it read only, we need that information as much as we need the wiki.
Your frustrations are completely understood. You are however free to ask any questions you may have here and get your answer that way.
