It went into read-only mode back in October apparently because the owner had mental health struggles, and the site hasn't come out of read only mode since.
And plus, even if she had mental health struggles, why does that mean making it so that nobody else can use the site? Doesn't make much sense to me.
I go there to check the results of issues and because the site is locked down, issues aren't updated there. I also wanted an account, but that isn't possible.
