As the language of your blog is Turkish, I recommend adjusting the language settings of your site:
First, adjust the language settings for the interface seen by readers. This will change the language of your tags into Turkish automatically:
You can also change the language of your Dashboard by clicking Users. In your Profile settings, you'll see the label "Interface language." Change that into the language with which you'd like to maintain your site.
I need to copy and paste translations. How can I do that?
You would copy the translation you mentioned in your first post: "How can I import unapproved translations to my blog from Glotpress?"
Then, you would paste it into the window of you Post/Page editor.
Please let us know if you have any other questions. Thanks much and happy blogging!
