Thanks for the update and enthusiasm, it was good meeting you last weekend in Amsterdam!
When it is more common in your country, .org.th
is of course similarly OK (I assume you have a similar situation as in the UK, which uses .co.uk
In Amsterdam we already shortly discussed the reformatting of the existing Thai monument lists (on th.wikipedia), could you link this as well from the page on Wikimedia Commons? I also see that you copied the timeline from the Dutch competition. Probably it is best to copy the updated timeline on http://commons.wikimedia.org/wiki/Commons:Wiki_Loves_Monuments_2013/Timeline
. Please bear in mind this is still a 'perfect' timeline, for a perfect world. As you started later, it is to be expected that things happen later, and that you may have to skip certain steps.
