d00t

To a company that i own theirname.com while they:

a) own the trademark
b) has unlimited legal funds

it was definately registered in bad faith, generates next to no traffic, but heck..i want a few bucks out of it.

They do not know I have it.
Best plan of attack?

Send a letter by mail? saying what?
Email ??

How does one approach these touchy deals?
