I used the contact form at http://classifieds.thaivisa.com/contacts/ because I found a picture in an ad that is copyrighted to me and was used without my authorization (and a "thaivisa.com" watermark was added to it, nice touch).

So how do I know if my message was correctly sent or not???

I use IE 9 on Win 7.

Try again, and see if it says the same thing

also please email the link for the ad to support at thaivisa.com
