I thought a good way to learn to use wordpress to build a website would be to sign up for wordpress.com, as i do not know php and will be learning as i go. But it seems all the functionality I want to add to the site (buddypress, forums, etc) is only available at wordpress.org. Is this true? I just bought a 99 dollar package when signing up, would this be transferable to wordpress.org? If so, I would just as soon do that. Blogging is great, but my plans are a bit more robust.
Please advise if you can, and many thanks for helping a newbie :)
