just a short question: Do we need all languages for roll out a release for Joomla 1.7?
We are not waiting all languages for release. But while I am finishing work on component and its modules this is good time to update translations. I am not going to release component without modules (at least JComments Latest) or basic translations.
Wouldn't it be better to roll out the new version and update languages later?
There are many users who want to use this extension but doesn't speak english or some other language which is already updated. We must remember about them too...
As I wrote before I do my best to release JComments ASAP. I am very grateful to all users who offer me help with translation or have already helped. Be patient and in nearest time we will get the new version of our lovely extension

I am not going to loose time for implementation of some unimportant features. But I am sure that you want to get high-quality and stable extension so stay tuned.
I used to do translations for my extension manually by emailing language files, and I can't express how much easier it is to have tranifex manage the translations online.
Thank you Matt, but I will try to use it with next version (because now I do not have enough free time to learn how this works).
And some words about development process. For last week we've updated 3 translations (Turkish, Romanian, Hungarian) and fixed 1 bug. Create first version of new module JCommens Latest Commented which allows to show list of most commented objects - not only from com_content as it was in old versions, but from any extension where JComments is integrated. So you will be able to show list of most commented items from K2 or VirtueMart. Started work on new version of JComments latest... Stay tuned!
