Hi, I just bought the software and it certainly has its plusses, but I had no idea that the ad sizes would be so limited. I had faith in the website promotion that 100 templates would mean the availability of most standard web ad sizes. However, nowhere on the site could I find a comprehensive list of the sizes available in the package. I bought it on faith. While it's not necessarily a mistake purchase, but I really do need more standard ad sizes in order to make the investment worthwhile.
