What is the process for obtaining a Thai visa after exiting the country for paperwork issues?

Might help someone who also messed up their paperwork this year: I exited by road on 15th to Savvanakhet. Applied for visa day 1. Cost 2000thb. Submitted app form, kor ror 2, copy of wife's name change cert, copy of her I'd and house book, copy of all of my passport pages and 2 passport photos. You will need to go to visa on arrival at Laos with another photo and form, then pay 50 baht for the bus accross (don't exit thailand before buying a ticket or face some stern words from the IO who has to go get it for you, oops). There is a good hotel called machiato coffee which is 30 seconds from the office and has everything you need, except the WiFi is a bit slow. Thanks to the advisers on this page that helped the trip run so smooth.
