Thank you for the advise FunkyDexter, I will generate the codes using my rnd key maker and store them in a txt file, i'll post keys on my website which in turn people can use them by emailing me back the code. Now am limited in programming skills as am just starting out, so all I want to do is the codes I get back is to paste them into a, say a validator program that says the code has only been used once, making sure that they dont get used twice. Is there any skeleton code I can use and build upon that's up to doing this or do you know a easier way of doing so.

Thank you in advance.

I am BaSiC
