I've got a few questions about logos. It seems you can download several from this site. What I don't understand is, how do I customize the ones I download? For example, there's one called Phone and 2.0 Tux that says something like "Reward if returned" with a fake phone number. I think something like that would be handy, so if I download it, how do I go about editing it so I can put my info in there? Or do I have to start from scratch? Thanks for any help you can provide.
