...Have you seen the really nice dictionary (http://rihannsu.theari.com/)? It's basically the dictionary you already have, but iirc there's written!Romulan (as in, how to write it) hiding in there, and some cultural stuff as well, though some of those links dead-end.

Uh. It's basically my thank you for writing this. It is totally mad awesome and I pimp it everywhere I go? Er. XD Klinhae arhem.
