WordPress.org

When would I use this?

When developing a new WordPress-powered website, and you need lots of pages and posts to structure the site around.

Can I create multi-level page heirarchies?

You can create top level pages and subject. We can't really go deeper than that, unfortunately.

I entered a really big number, and now nothing works.

Doh - didn't I warn you against that? WordPress can only handle a certain number of pages (my install usually crashes after about 15K). You'll have to access your database via phpMyAdmin or a similar client, and clear out the wp_posts table.

Can I add tags to my posts?

Not at this point. That'll be coming in a future release.

I only want to delete some but not all of the pages auto-generated

You have two choices. You can either go through and delete pages through the standard WordPress interface. Or you can go into posts you want to keep and remove the dummy content custom field. Really simple!
