We very much like your idea (Entry #98), but because the logo is blue, it remembers us to Facebook. Could you give it a try in the green which we have defined?
Could you also add a hyphen? Because the address ist www.buchhaltungs-forum.ch ...
Now we prefer your Entry #123! Could you may be create a blue version of this? Since the white space in the bubble is not that big anymore, the Facebook-Thing might disappear. Could you also do a variant with the text on two lines (the hyphen should be on the top line).
