Please consider designing a logo emblem - to allow for companies to use this instead of the copyright blurb. Companies should have the billing on the bottom for their content. The purchased software is impled to copyright laws - your advertising dollars should be alloted to promote your software not customers site. A " powered by" icon is acceptable and industry recognizes this as reasonable solution. THe copyright should be reserved for the customers content.
