Looks good. I couldnt find it on the site though, but does it come with Lifetime support/upgrades? As I know paypal is adding in new things all the time lately, so will the program be updated overtime to reflect these changes and keep it up to date? And if so, will it be free to upgrade?
Nice, neat looking script, hope you don't mind a suggestion but you might want to add some error checking for the username field to tie in with WHM's requirements (max 8 characters, can't start with a number etc) else i guess the account wouldn't get created.
Looks good though, alot of people often post looking for this kind of thing.
