Thanks to all the warmhearted friends in this Forum. I report my new update of my 485. A lot of people know the Oct 3's RFE issue: email notice but no mail notice. Follow a Wenxuecity's friend's method, I sent a Fax to TSC/RFE yesterday (Veteran's day). Today, I check online status. The LUD was changed from Oct 4 to Nov 13, but message the online status remains the same so far. I may have missed their phone call this morning. They may call again. Anyway, new LUD following my FAX implys IO has accessed to my case, positive sign. Let's see the next and hope the best.
