The logo must be sharp and not too cluttered. I have preference towards green and grey as colours, but will definitely consider other colour combinations. There must be some sort of loop concept in the design. The loop is effectively the circle of friends this site will help you to make.
I have supplied an attachment "green_icons.jpg". Please note - all icons in this attachment are subject to copyright law so cannot be directly copied.
In an ideal world I would like the green and grey world/circle icon (bottom line, 2nd from right) as the main logo. Perhaps this concept could be changed so that the dots/ nodes are turned into people and the circle tuned into a globe....
The text "crewloop" for the logo could may be made up of letters similar to the C in a circle (2nd from top line, furthest right). Again this is subject to copyright and so should be used as inspiration rather than direct copying.
I have created a lightbox in istock for other concepts that have relevance to crewloop
If you need any further design assistance let me know.
Best of luck,
