Ah! Sorry, you're right, we should have said something.Well mainly I was just wondering what people thought of the logo I made.
The logo isn't bad, not very colorful ( ), but not bad. The major problem with using it, and any logo submitted by anyone else, is the copyright angle. Since we don't own your image, I don't think we can use it without written consent from you. Even so, let's not pursue that at this time.
The logo I presented is an obvious variation of the one we already own (and because I "work" for TFL, it automatically belongs to TFL), there is no copyright issue to worry about.
