Learning the Thai alphabet isn't as hard as everyone makes it out to be. We adapted our cool kanji/hanzi learning game to Thai. It's got hundreds of everyday words and is great for learning to read the Thai alphabet.
If you're completely new to reading Thai, you may want a quick review on Wikipedia. It's not too hard though! Just consonants and vowels and tone markers. We also have some excellent reading Thai videos.
