Here's my problem.
I would like to send an Html christmas card to the registered members of my own forum but I am unsure where I stand as far as Anti-Spam legislation is concerned.
The site is hosted in the USA, is registered as non-profit .org but is amdinistered from the UK. Would the UK or USA laws apply ?

Also, I do not include express permission in my TOS to send emails to the membership. The registration process only requires the use of a genuine email address to send the password and username to. Would I be breaking the law if I sent out a "Merry Christmas to all members" type email?

Puzzled and confused    

Just to add as Katrina1 covered it basically Good though the laws based on our servers are managed under California law USA. Feel free to read our terms of service here:
