I also still don't have access to the Lounge (for the in-crowd), I'm getting closer to completing the Rising Star bonus.
If you still don't have access to the Lounge (or did not receive info about sign up for the Lounge), you may wish to look at what I posted a few days ago at this link: https://community.ibotta.com/t5/community-ideas/in-crowd-lounge-link-to-join/m-p/19659#M3458
How many items do you need to complete ICON?
@LK10: In response to your question, the people who received an invitation and joined what's called the In-Crowd and also referred to as "insiders." They are really a sample group of ibotta users who are participating in a beta test-program from February 1-April 30. Their first bonus is Rising Star, then ICON.
Hope that help you understand a bit more!
