After trying this out for a while I'm going to break things back out again. So the Politics and Social Justice section will be put back on that top, bumping down the Open Discussion section and breaking out all of the subforums.
As @Eric has said, this has been moved to Arkham and renamed to Archive.
However, you can still post there, and create threads there, and have discussions there, as I daresay some matters on MR will still remain of interest (just, not an all consuming interest) to many, if not most, of us.
Yes, many of us are refugees, or exiles, of one sort or another from MR, but there is more to life - and this forum - than our (sometimes strained) relationships with MR, and it is time to move on and focus a bit more on other stuff, topics and things, such as "Life, The Universe, And Everything".
