I have been using WordPress for some time now and I love to application. I would like to create a portal using WordPress. This means that I would use WP for commercial/my business use. I will put banners/ads classified and other things. And I hope to get some money for it.
In the codex says that WP is free. Does this include the above use/purpose? Can I use it to create my business portal for free? Will I be breaching copyright?
