use of the clan crest and tartan on on-line website

[Tobus]

Keep in mind, also, that a clan tartan and clan crest are representative of a group of people, not just yourself. In using these identifiers for your own profit-making purposes as a company logo, you are sort of abusing the idea of what clan association means. Only the chief of a clan has license to do that. Without his permission, it's not a very nice thing to do.

Sorry if that is too blunt, but I figure it needed to be said.

What about making your own unique company logo (and tartan) that resembles a Scottish clan motif, but isn't hijacking actual clan symbols?
