Back in the days, this site was just physorg.com's forum. It still has a "relevant posts" block linking to here. But in practice, it is trivial for any site to have such a block without any formal relationship between the two sites... So I wonder, is it still associated with it now? Are there any common people among those responsible for the two sites' administration and development? And if yes, a subquestion: why has phys.org deleted their old user database (maybe quite a while ago now, been some time since I tried to login there, and now I find that I can't)?
