I cannot do the graphics myself, Maybe for one of the designers who may see this or you may have some designers you know to share the idea with for development.
I am guessing you accept and promote people of all nations, Though the languages you promote may need a member of that language, putting those technical things aside.
I would suggest a representation of the world map or a globe With a representation of people from all locations, on the map/globe. Above this a united symbol Similar to the Olympics banner A symbol of coming or working together. Or hands reaching out and connecting across the world.
Some nice ideas here, thanks!
hmmm yep some real good ideas here
