Okay, I've had a chance to do a little more research on that suspicious email sent through our group. It looks like the website contained in the message doesn't contain any malicious code. In other words, if you did click the link, your computer probably wasn't harmed, at least as far as I can tell.
Apparently, it was just some advertising scam and nothing to worry about.
I hope my last message didn't cause anyone to freak out. But this whole episode does reinforce that old Internet warning about being careful about links you receive from strangers. That fact that this one slipped through Meetup is a bit of a cause for concern, and I am contacting Meetup's technical support to see if there's any way to prevent this from happening in the future.
Again, sorry for any inconvenience (or any worry!)

I haven't quite confirmed this (I only just checked my email a few minutes ago), but it looks like our group was spammed this morning with an email containing nothing but a link to what appears to be a Russian website masquerading as a CNBC News affiliate. I strongly urge you NOT to click on that link! I'm not sure what will happen, so your safest bet is to just stay away.
I've contacted the sender and warned him that his computer may be infected with some sort of malware. I also warned him that if he sent the link intentionally, he will be banned from the group if it ever happens again.
I hope that's the end of this. Let me know if you have any more problems!
Sorry for any convenience this may have caused.
