Many have reported issues with TT trying to access the forum. We believe it has something to do with the new SSL certificate. The forum is now https://, and TT does not automatically redirect to it from http://. We are looking at what we need to do on the forum's end to fix the issue. We apologize for the inconvenience and thank you for your patience.
Maybe just gremlins after all? Who knows with this stuff. Appears to be functioning fine now (using Samsung Galaxy S4 and TT).
