You can create a request for connecting your account to the already exists player information.
For that please provide your social media contacts (tg, vk, something else), so the admin will be able to verify your identity.
Verification usually takes a couple of days and once it has been done you will be able to change player info (name, city, etc.) and you will be able to apply for tournaments with simplifying flow.
