Drupal 7.x

I made a copy of Bartik, renamed the folder and the theme in the .info file and placed it in the sites/all/themes folder. Then I added the "base theme" code to it.

Now my site will not display. I'm getting the following error:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 35 bytes) in /home/content/12/6477012/html/infomance/includes/theme.inc on line 99

I'm setting up a new Drupal 7 site for our school for next term. Every parent, student & teacher has a Google Apps for education account, and I'd like them to be able to login with the same credentials.

I'd like to be able to make it so, if they're logged in with Google they can just click-in, or if not go to Google, login and then they're automatically logged into my Drupal site.

However Drupal's default OpenID module doesn't seem to do that.

Any simple way to allow users to use their GoogleIDs to authenticate?

I'm trying to create a collection/bundle of nodes.

im newbie here.
I just created a website and my website doesnt show anything except
except : index of " drupal -7.2, wysiwygy....."
all of my puplic html folders show up there.

First, I would like to ask you guys how to make it really display only My default front page :
http://mydomain/drupal-7.2/
when people click on my page ( puplic.html folders won't show up any more )

I am using Ubuntu 10.10 + apache2 + php 5.33 + mysql + Drupal 7.

My problem is the URLs used by Drupal are similar to the following one:
http://localhost:8080/drupal72/?q=node/1.

I want to remove the ?q=node/1 and replace it with some name /user or /book.

I'm looking for this functionality http://drupal.org/project/popups_reference but can't find a way to do it in D7. Can someone give me an alternative way to do it or point me to right direction how to implement that programmatically? Thanks in advance!
