On #2, not a big fan of the reflection, and it doesn't have "PLUS". #3 isn't bad, it's simple and I like that aspect of it, I will definitely keep it in mind, not 100% sure if it's what we're looking for, but it's not bad at all. Thanks for submitting!
I like the direction you're going, but #24 the icon looks too much like a pill/medicine type image, and the 3 interlocked rings almost has too much of an Olympic feel. They're simple, to the point, but they just don't stand out much, it would be hard to brand 3 rings and the text looks nice, but it's kind of uninteresting. Thanks for the new submissions
