Just a heads-up, it looks like the “with your iNaturalist account” option for logging in to the forum is currently broken, likely due to some changes on our end made last night.
We’re looking into it, but until it’s fixed you may need to create a password for your forum account and then log in with it. You can do that by going to https://forum.inaturalist.org/login and clicking on “I forgot my password”. Then you should be able to log in using your username or email address and the new password.
