problem for me

How many days does it take on average to change an offline club owner? maybe i can't do it

Did you follow the information from here?

ya but i quite dont understand

👍hmm , I also want to know.

The pertinent sections talk about super admins but I believe the new owner would need to meet the same requirements.

• Eligibility requirements for Super Admin status
• What if the Super Admin is inactive or has left Chess.com? 

i know, but mine club owner hasn't been online for a long time, now i want to be the owner of that club, how can i do that and is it completely legal? (im a S.A)

• Create a new topic in the forum and invite club members to vote on whether to replace the inactive super admin and who they should be replaced with.
  Once a decision is reached in the forum, contact the Support team and provide a link to the forum. Support will reach out to the owner - DM and email, and wait 48-72 hours for any feedback. Then, the Support team will be able to replace the inactive super admin.
