I logged in moodle.net and could not login in moodle.org.
how to resolve.
I'm assuming you mean that you logged in to moodle.org but couldn't log in to moodle.net, right? I just tried and managed to log in to moodle.net, so hopefully it was a temporary blip which is now resolved. However, if you encounter the problem again, please email firstname.lastname@example.org.
