Sorry Patrick, meant to add it might be worth you considering a name change before you get in too deep..these guys would have a strong case to suggest that you are attempting to pass off.

With a little bit of imagination you can come up with a much better name. Corporate ID and branding is something I do/have done and using a hyphenated name with a .net extension ain't 'good'. One thing that has changed is length of brand, back at the 'birth' of the inter web it was all "if it's not four letters you're dead" now comparethemarket, money supermarket etc have proved that to be wrong. Thinkorswim was ace as a new fresh brand, find something that works and is not compromised by search engines..
