M'ath, zhey Arcix!
Welcome to the Tongues of Ice and Fire forums. I hope you enjoy your visits here. Although the forum itself is fairly quiet, there is a lot of work going on in the wiki section of this site, especially in the Valyrian languages. Qvaak is always happy to do linguistic analysis on ideas you may have, and his insight into especially Dothraki is simply incredible.
If you have any questions, please don't hesitate to ask them!
