What are your opinions on contacting members
 

When I get a new signup, I like to email members and thank them for signing up and stuff like that. Is this a good idea or a bad idea? Some may like the fact that the webmaster takes time to email them and thank them, while others may find it's an invasion of privacy. Thoughts please.

not at all an invasion of privacy. I think it's a very good thing

It's good if you dont abuse of it (see spam)
