Hi Akin
As requested last year, every team coordinator first needs to register and login fedora.zanata.org, and then be assigned coordinator role. Then the coordinator can start approve his/her team member as translator/reviewer.
According to the team page [1], Onuralp SEZER is your team coordinator.
I can't see him in the user list on fedora.zanata.org yet. Please contact him.
