Can someone else file my 90-Day Report in Thailand if the online system is down?

The user inquired about the possibility of sending someone else to do their 90-Day Report due on April 12, given that the online system is down. According to community comments, another person can indeed file the report on your behalf without needing a letter of authority, as long as they have your passport, the filled-out TM47 form, and the last report slip.
