Always good to receive an email like that.
What is really interesting is further on in the email, it outlines what they’ve got in the works: a system of integrating their website [probably the best mod website out there for The Elder Scrolls mods] with a program. The program would work as a client for finding, downloading & automatically installing mods. It’s currently working for Oblivion & Fallout 3, I have no doubt that they’d get a Skyrim [only ten days away!] one in due course too. Great promise.
