Canceling a BOINC wide Team

[seeke...@gmail.com]

I no longer wish to belong to any team and or support   and I do not wish projects to automatically assign me to a team that I do not wish to support any more.  In the website for BOINC wide teams, the option to cancel a user account and team is disabled and some project will not answer my request no to automatically assign a team in accordance with BOINC world wide team.  What should I do to cancel my user name and team from the BOINC wide team?
