I have installed the YUM Release Candidate 3 this morning, and followed all the instructions for installation and found the following irregularities:
[i]9.) Click on the ‘update Icon’ (the pencil) of your administrator User.
Change the Password to something more safe than ‘admin’. Click Save.
[/i]
This could not be done before changing the URL to: 127.0.0.1/testdrive/index.php?r=user.
Also, there are a lot of functionality that does not work, when I try to change the password, it complaints that the password cannot exceed 16 characters, even though the password is only 8 characters. I was unsuccessful at changing the password.
I could not assign a role to the demo or any other userid, it complains the that role is unselectable. I cannot send a message to anybody as nobody appears in the To pick list. That particular screen implies that you can only pick amongst your friends even if I am the Admin account. The Friendship module does not appear in the admin menu even though it is listed in the modules array.
I have not tested extensively, but I suspect that there are a number of other things that do not work as well.
