Overture newbie here...

A Google AdWords user needs help

[BriGuy]

I just added Overture to my PPC advertising campaign (I started with, and continue to use, Google AdWords) and I was hoping to get some feedback on how it actually works.

My initial impression of the service is that it isn't nearly as organized as Google. Is there any way to subcategorize search terms together below the first category (like a BlueWidgets 2000 model category with a collection of terms underneath a BlueWidgets main category) like Google has? I loathe to imagine how much harder it will be to pore over my listings without this extra layer of categorization.

Secondly, I'm having trouble getting any click information to show up on the Manage Listings/manage bids page. My Account balance seems to show that I've gotten a great deal of clicks, and my account summary page does too, but nothing shows up on the manage listings page. Is this just a hiccup from Overture?

EDIT: I just got my clicks information to show up. The obsessive, refresh-happy AdWords checker in me is overjoyed. :)

Third, I'd appreciate any tips you guys have regarding Overture from the perspective of an experienced AdWords poster. What differences should I be aware of? What featues set Overture apart from Adwords (and vice versa)?

Thanks in advance for all your help. :)
