You cannot delete your account, but you can deactivate it anytime you decide from the account settings. Deactivating your account means losing access to your meetplace, projects, meetings, files.. etc. If permitted, delete 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.
