I like the linking of communities feeling I get from #1 (three circles of people coming together). I would like more options to express that same message, possibly add interlocking communities.
#19 is definetly a good concept. Bringing multiple groups or communities into one large one. Modification: Change the coloring of RiteByMe to be same sequence as "1 (Blue, Grey, Green)
Are there any other options on designs that spread the same message?
