Redrawing because someone hasn't responded yet sounds like a very A hole thing to due at this point considering its only been what like a day or so and people do have lives. I think that its not only unfair as it wasn't listed in your original posting that they had to respond within a certain amount of time and second that your inviting all kinds of trouble and possible regulations of these type of things in the future by doing so.
i did state that i need to be contacted via PM within 24 hrs so dont get all mad. i am giving these codes out for free so i wouldnt be complaining. there are people out there that have be PM'ing for these codes so i feel they want them more than the people that have not responded yet.
