I can usually figure this stuff out without much of an issue. How does Drupal lend itself to learning from scratch? I've got experience installing and setting up Worpress, Movabletype, Gallery1 and 2, and PHPWebsite. Do you think Drupal is comparable to these programs in terms of configuration and use?

I also noticed they are in the midst of doing a version upgrade but only have the betas available yet. How are the upgrades usually handled. Simple file replacements?

Thanks!
