You cannot delete your account, but you can deactivate it anytime from account settings. Deactivating your account means losing access to your meetplace, projects, meetings, files.. etc. If permitted, delete the content you'd like to remove before deactivating your account.
You can reactivate your account by contacting the admin or owner of the meetplace.
Note: If you are a meetplace owner, you will need to transfer your meetplace ownership first to another active member before deactivating your account.
