I was referring to mindstim, yes I like it too. My brother took it when he visited me. I was wondering if anyone payed the $24 to get the rest of the Brain Energizer. I have been using it while studying algebra and it has helped me to concentrate longer. I paid for the password, you have to download the newest version at a personal site belonging to Jon Paulone. The site was unavailable, so I don't know what the deal is. I hope I haven't been taken, oh well, it happens. I'll post if I'm able to get the whole program.
