When you are in your locale page and click on the "qbittorrent" resource
a popup appears. There you have several options. Choose "Upload file"
and select your .ts file. Transifex automatically imports .ts files.
Also if you select "download for translation" it will export the strings
to a .ts so you can load it into Qt Linguist if you want.
Tip 2: If you are Coordinator you can accept/deny JOIN REQUESTs of new translators to your locale. Also if a translators does a bad job at translating you can delete him from the team.
If anyone else has any tips please sent it this thread.
