There's a reason why chameleon submitter tries to copy everything dreamsubmitter does.
And as always, i will put my money where my mouth is and give ANY chameleon or advanced submitter user a FREE 1 MONTH trial of dreamsubmitter to see exactly why it is that damn good. I guarantee anyone that takes me up on this will not go back to their previous software.
