Zorah,
We are currently working on dictionaries for the Valyrian languages. I don't think you are going to see them right away, but probably in the next few weeks. Those of us working on the Valyrian language learning tools are looking at some different ways of doing things. Some people like the traditional dictionary, while others prefer something that is online. Both have advantages and disadvantages.
The language's creator, David Peterson, has become a very busy man, as his success with Dothraki has brought him much more 'business'. David I feel, is quite committed to Valyrian, but he is releasing information a bit differently than he did for DOthraki. Much more of it is concentrated here, and (especially) in his blog at
www.dothraki.com You can always join our IRC chat at 7 PM Pacific time, every Monday evening. You can use the IRC client on the main Dothraki page, or your own at irc.dothraki.org, #dothraki
The Valyrian wiki is under intense development at the moment, and will be opened to users as soon as the basic information has been 'installed'.
