I just got a couple of emails… one from the Eventful.com staff (posted here) and one from the guy who recommended Eventful to me in the first place, Jonathan Coulton:

Hey Matthew,

Very surprised to hear that, I’ve never heard any complaints from my fans, and I know they’re generally very careful about being spammy. Are you sure that’s happening, and have you contacted eventful about it? I’ve found them to be very helpful in the past.

If you’re getting emails from Eventful.com that you don’t want, I’d suggest checking the unsubscribe links and reading carefully. I can’t find any evidence that they’re spammy. In fact, they seem to be fairly reputable as far as online services go.

Sure, they want to send you mail, but I can confirm that they do indeed let you opt-out once you’ve created an account. If you still have any problems, though, please let me know!
