@SIREldarB Hello mate and welcome to the Global forum.
As you have seen for yourself , every new manager that is signed on OSM is able to change his email at his game profile only after 30 days. So my questions to you would be:
- Why do you want to change your email? There's no need for you to do so. And also,
- When you gave your email address the first time on your profile you must have got a mail - answer back, asking from you to use a specific link in order to confirm and activate your email. Did you do that mate? Did you activate your email yet or not?
