I've found that this isn't permanent. If you create a new account, you can't add pages right away, but once the account is three weeks old or so, you can add pages. I did one webs page for a mod journal and it didn't work, we couldn't add anything. I just tried it, and it let me add two pages AND let me customize them. So maybe there's a system fluke that will let you do it once the account is X# of days/weeks old.
