EmailingIf you wish to email, the address you should send the mail to is Psy at GTA4 dot TV, obviously replacing the at and dot for their respective characters. This is for spam prevention, although it won't really work anyway.
You MUST use a descriptive subject for your email. Due to the large number of emails we receive it is often tedious to have to read through a whole email just to find out what it's about, so unless emails are subjected properly, many of them may be discarded. Useful subjects could be "Website Affiliation", "Website Problem", "GTA4 Question", "Forum Problems" or "News Submission". Feel free to use your own as long as it will allow us to categorize what your email is about more easily.
