CorkyO's tutorial page really is under construction. About half the page is blank.
The cache tutorial is part of the material currently unavailable
The pages are not blank, I just use a lot of images in my tutorials, so the pages take a while to load. Sorry about that.
Here are a couple direct links to the articles so you will only need to wait for six to eight images to load:
Working with ObjectDock 101 - http://corkyo.wincustomize.com/articles.aspx?aid=82930
Clearing the Cache 101 - http://corkyo.wincustomize.com/articles.aspx?aid=82461
Note - my tutorials were written before Jeff (OD+ developer) included the new 'library' folder which appears in 'My Documents' of your account. You can use either the folders shown in the tutorial (which are in the ObjectDock parent folder) or the folders in the 'ObjectDock Library'. Please note that for ease of use, it is best to use one or the other - not both (although possible, this makes troubleshooting an issue).
My other tutorials on ObjectDock Plus outline the individual creation of a non-tabbed (zoomer) dock, a tabbed dock, a system tray dock, editing a non-tabbed (zoomer) dock, and editing a tabbed dock.
I hope this helps, and apologize again for the load times of my not so small images.
