Turkish is my first language, so I thought I'd let you know about this.
So the current message is "Karşılama, <user>!" which is not a correct translation. That word literally translates to "greeting (verb)". Whenever you say "Greetings!" to someone you greet them, right? Yeah this is the word used in here, and frankly it's not a right usage.
To be fair I don't blame anyone for this translation because there isn't an actual word for "greetings" in our language. Therefore the new welcome message should just be a simple hello.
The new message should be:
"Merhaba, <user>!"
