I've used Google Translator Toolkit for about a 30-page project. The interface is simple and comfortable to use.
After completing my translation tasks, I wanted to export my private translation memory. The Toolkit only let me download broken TMX files(formatted correctly but with no content body).
I attempted to contact the Google Translator Toolkit project customer support regarding the issue, but they never responded to my message via a contact form. After a week or so, I repeated the same thing, reminding them that it was the second time. Again, they've never responded.
So after a few month (that's today...) I tried the memory exporting function on Google Translator Toolkit. It seems it's working now. Although I haven't looked into the TMX file in detail (thus don't know if it's really working but the file size seems about right), I appreciate the effort to fix the problem.
Then again, I wonder what's wrong with their poor communication. No response, no announcement AFAIK. Maybe they are just too busy making the Toolkit work, or other tasks came up with higher priority. I myself work on my websites for living as an engineer, so I guess understand such situation partly.
After all, Google Translator Toolkit became better, so thanks for the good work, to whom it may concern!
