WPyogi on "Word Press functions"

WordPress can be used for whatever you like - blog or not. There is not a separate version of WordPress core, but there are two ways to use WordPress - see:

what software here at IPage is the best for simply creating a plain website with text and pictures that can support audio files being played and paypal links to make payments for services??

WordPress can certainly do that - see:

EDIT - note that these are WordPress forums, so if you are asking about iPage, you need to ask them.
