Thank you for your entries. Nice idea - but consider that whenever you use a cross it has to be a white one.. (Switzerland's flag has a white cross on red ground; you made us the red cross organisation)
now you're coming our way! I like entry no. 173. The shape of the cross still needs a little edit... (maybe you'll have a look at an official Swiss flag as the cross has certain measures). Drop the refelctions - it's too playful.
I like Entry #183 - yes please get rid of the registered mark and reduce the size of the logo part; it's a bit too large in proportion to the font size
