::@andy, I found both you site and IRs helpful, with yours focusing on administrative practices, and Isaan Record focusing the practical effects on both administrators and administered. I feeling there could be a fruitful exchange between ChAmTb and IR that would work to the benefit of Wikipedia, as well as to  visitors to your site should you make mention there of IR''. They focus on Isan while yours has Thai-wide applicability, but as of yet I know not of any other scholarly websites with a direct bearing tambons. I also feel this information could be of help to other editors interested here, which is why I posted here rather than there. It is helpful to me when I find someone to help me say what I mean — one of duties of editors.
