Those of you living in Thailand are well aware of immigration's 90-day Address Report requirement, which can be done at any immigration office.  Some may not be aware that you can do the whole thing online.  The programmers have done a good job with this one.  It works perfectly and can be done on a desktop computer, mobile phone, or tablet.  No more trips to the immigration office.  Those who live nowhere near an immigration office, no more mailing in.
What you do is log in.  Here is the URL:  https://tm47.immigration.go.th/tm47/#/login
Use that URL on whichever device you have or prefer.
If you're doing it for the first time you'll fill out the simple "Apply" form.  An Email will be sent to you with a password.  Save that password, although after the first time you log in your password will probably be saved.  You probably won't need to reenter your password unless you change devices.
Once you log in, now you'll fill out the Address Report form, which is very simple and actually requires a bit less information than the form you fill out if you go to immigration.  For instance you won't be asked for your arrival card number, how you arrived in Thailand, etc.
After filling out the form, you will submit it.  Not long after you will receive an Email telling you your submission has been received and accepted.
Not long after that, usually within an hour or two, you will receive another email telling you you have been approved.  Then you go back to the web site, click on the green "Status of Application" button.  The page that pops up will contain the approved form that you download (PDF format), print out, and put into your passport after removing the last address report form.
If you don't have a printer you can copy the form to a flash drive or take the device itself to any copy shop and they will be able to print it out for you -for about 10 baht.
After you have done your first submission, now you will receive an Email from immigration when your next report is due.  I'm glad they do that now.  They make sure you don't forget.
Who knows?  Maybe one of these days they'll come up with a way to do the Retirement Visa extensions entirely online, but I'm not holding my breath for that one . . .
