OK a lot of developers out there use CMS to design their clients' websites.
Among them wordpress seems to rank amongst the top five and I can totally see why.
This thread is for all the useful resources you know of using wordpress.
I'll start this one off.
An absolute must for beginning with a blank theme framework is the one provided by thematic.
So many widgets and a stripped down css with a beautiful Superfish menu.
Super for tutorials especially how to create a portfolio section. A must read.
Another resource for online videos.
How to create a stunning quicksand like filterable portfolio.
If you are designing an easy background control panel for end users and you have php5 support the options tree plugin is a must
Create quick and easy shortkeys from the html editor - great plugin
A great jquery resource.
Where would we be without shortcodes ultimate plugin... I don't know
yd recent post widget plugin.
A great way to add a touch of class with various different fonts.
An absolute resource.
Sliders, a few come to mind.
Nivo slider, piecemaker 2D (flash)
And a brilliant free template to download if you sign up to their newsletter
Great to look at the backend code if you intend to become a developer.
