As many of you know, the forum engine has been acting weird this weekend, desynching us from sending p-mails, sometimes telling us our post time has expired, sometimes posting us as though it's late April 2012.
Migrating the forum to a new site didn't fix this problem, though it was a good try.
I'm currently experimenting with whether having logged out and logging my account back in manually (rather than by cookie) re-synchs my account with the forum server.
So far, so far, although it's more of a negative deduction test: if it fails, then I know it didn't work.
Edited to add: this post worked, sent 11/11/18, 9:53pm my time. (I mention this on my test post by editing after posting, to see if the system is retroactively redating member posts backward. I haven't caught it doing so yet, but I saw some minor evidence that way earlier today.
