There is no way for me to tell Meetup that their site is down. There's no contact page, no e-mail address, no suggestion box, no chat, no nothing. I want to help them get their business online but they have made it nearly impossible. Literally the only e-mail address I have found is for their recruiting/jobs page.
This problem is much larger than just one website. I've seen this dozens of times on huge websites over the past two years.
Years ago, a company I worked for was actually serving malware on their website, because a server got hacked and we had no idea. Somebody found it on a blackhat internet forum and wanted to tell us, but spent hours trying to track down a generic website contact just to let us know.
People of HN: Please tell your job that their website needs a contact page, and somebody in the company who checks the emails and sends them to the right group. This isn't rocket science, y'all.
