Anyway, here are my top 5 tips for your new Meetup group.
Disclosure: This worked for me from 12/14 to 12/15 and for entrepreneurial type meetups. It isn't guaranteed to work for yours. Be smart, take some or none of my advice and most importantly. Keep pushing forward.
If anybody has other suggestions please give your tips in the comments, would love to improve with you guys :) Check out my group Startup Denver and let me know any questions you have about how I grew it.
