There doesn’t appear to be any way to delete your forum account. I need to delete this account (it hasn’t been used since 2007; Comodo must have changed their notification settings, so I just started getting emails).
This forum doesn’t support deletion of accounts for some reason, it does however allow you to remove the data from it, I believe you can PM a moderator for more help regarding that, or perhaps a moderator will reply to this topic.
As far as your account settings you should not be receiving anything from Comodo all options are unticked.
As your last post was December 2007 please PM me link
