By being part of the UNOFFICIAL re:invent Slack group, you accept and agree to abide by these simple guidelines:
Respect everyone here. We will not tolerate harassment of any kind.
Do not violate any NDAs you have with Amazon or any other entity. Remember that everything in Slack is public.
Do not scrape the member list for email addresses to spam. Anyone or any vendor caught doing this will be publicly shamed and reported for violating the CAN-SPAM Act.
Have fun. This is an experiment and could be shut down by any number of things so enjoy it while it lasts.
