How can my husband submit his first 90-day report for a Non-B visa in Thailand?

The user is inquiring about the process for her husband to submit his first mandatory 90-day report for his Non-B visa. They attempted to register the report online, but it was rejected with instructions to contact local immigration. There's a discussion about whether a standard authorization letter is needed if someone else submits the report on his behalf, with comments suggesting that previous submissions didn't require formal authorization but needed the necessary documents to be signed by the passport holder.
