We support Internet Explorer 6 & 7, Firefox 2.0 and Safari 3.0. If you're using a different browser (perhaps one provided by your internet service provider) it might not be compatible.
If you joined before October 5th 2007, you may previously have been prompted for a 'Ning ID'. We now ask for you to sign in with the email address you registered with, however you can still enter your Ning ID in this field.
Visit the Ning Help Center for more troubleshooting information and support.
