<ul><li>There needs to be, for want of a better word, a blacklist. There are some teachers that I would not take lessons from if they were the last teacher on Earth. Maybe they're too expensive, maybe they're a jackass, maybe I watched their video and I couldn't understand a word they said. This is even more important for students of English because there are so many English "teachers" that just shouldn't be on here; ones who cannot even put together a sentence, for example. Having these faces clutter up the search results doesn't help with finding a GOOD teacher.</li><li>Prices. It used to be that the headline rate in the search result did not match any of the (visible) lessons. I can't find any examples of that at the moment so this may have been fixed.</li><li>"From" is useful but "In" is better; but it's not an option. I don't want to learn German from someone who was born in Berlin but left for New York at the age of 3. I want to learn a language from someone who uses it every day. Nor am I interested in learning a language from professional polyglots, but the very useful "Native Speaker" language button deals with that... IF the teacher is truthful. (Again this is more of a problem for students of English. I haz seen manee Native Speekers of Inglish who clearly isn't (sic).)</li><li>Absence of a "Small Groups" option. If you're going overseas with friends or family it would be useful for all of you to be in a lesson together. However the only way you can find teachers who offer this is by searching profiles one, by one, by one. </li><li>The fact that you can't save a search profile, so eeeevvvveeery time you want to do a search, you have to reselect all of the options. This is even more of an issue if you're learning more than one language.</li></ul>

The lack of advanced filters is why I don't use iTalki. I'm learning mandarin and need the following filters: regional accents or geographic location in country (China is big!), and gender/sex (I want to hear a male accent). Without these filters I have a list of 1000 to sort through. Too much work.
