I did my "90 days notification" today online at 11:45 (Nonthaburi).
2 hours later approved via e-mail.
No sweat … :-)
Something new I noticed is the "REMARK" on the bottom of the approved screen where they write your last TM30 information. So it's linked with the TM47 database and followed up now.
CAUTION: I only mention this because if the new remarks on the bottom of this document. Just like Tod sayed, you NEED TO PRINT and keep in your passport the "next appointed" document.
