No so much to explain, this happened to me yesterday, and now at 17:45 hrs (Chilean hour), is happening again, with several observations.
No a problem to me, but it could be annoying to new users.
Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):
Weird. I was having problems signing in to the forum earlier today, at about the same time. The log-in screen just would not take my iNat user info (and was trying to force me to create a new account)—right up until it worked. Maybe they were related glitches?
