I send an e-mail with a copy of the post(s) ( with registered user information) or e-mail(s) ( make sure get the header off the e-mail as well)
to this address:

contact@conitec.net

That usualy all end up needing to do.
On your website/boards. never use your own ISP email address as a contact address btw. use one from another e-mail service. in fact never give out your own ISP account e-mail address, always use an alternate one(s) for e-mail.
