Drupal 7.x

Drupal has all these modules and internal APIS and functions. A majority of these module functions return data commonly in either an array or an object.

I'm working with a client that really like the accordion style menu system seen here: http://checksix.us.

I did some searching and haven't really found a module that will accomplish this. Plus, the client I'm working with said they really like the large pictures, the information that appears, and the ability to have a hyperlink, but they don't want to copy that exactly.

Likely a stupid question...

I have lost all admin rights to my site when I upgraded to 7.7... help! I am currently restoring it back before I upgraded. I don't know what I did wrong and need some assistance.

I still can edit pages but I can not see the Admin Tool Bar at the top... it's gone. Please help.

Is there a module where I can specify placeholders within the node body and these placeholders will be replaced by a certain value specified by the user? I'm not sure if tokens is appropriate for this.
