I really don't want to slam you but I have to say a couple of things. How could you *not* know that taking something from another logo is wrong? And then selling it to someone else, as your own creation, to use as their logo? You said you didn't know, that now you do, and you're working on a redesign. Good. You learned something and are trying to correct a big mistake. But that is something very basic that anyone who takes on the responsibility of getting paid to design a logo should know! It never ceases to amaze me how many people think that owning a plotter and software somehow qualifies them to be a designer. Not saying you're one of them. Maybe you are, maybe you aren't. The ones who do really make me wanna have a come-apart. I don't know why. Just does.
I'm not totally directing all of this at you, qmr55. At least you're trying and not storming off. That's great! But when I read your signature, "Truly elegant design incorporates top-notch funcuality into a simple, uncluttered form", I had to vent cuz I'm not seeing that you get that. Sorry. Keep trying and good luck!
