This site offers a look at various “secrets” about numerous features of InDesign, It’s content is managed by two self proclaimed “gurus” of the design world. The site offers a good layout separated by category (color, text, ect.) and offers posts by both the creators and users. It also offers links to tutorials and plug-ins, each being reviewed or recommended by the authors. For the hard-core designer there is also a podcast of InDesign-related jargon. I have found this site to be useful numerous times.
From the site: “Adobe InDesign is taking the publishing world by storm. But if you try to find reliable information about InDesign on the Web you’ll find yourself scouring Adobe’s site or muddling through dozens of other sites for a tip or two. Now that you’ve found InDesign Secrets, it’s time to stop all that muddling. Developed by page-layout guru David Blatner and “DesignGeek” Anne-Marie Concepcion, InDesign Secrets is your one-stop shop for all things InDesign.”
InDesign Tutorials
http://desktoppub.about.com/od/indesigntutorials/Adobe_InDesign_Tutorials.htm
This section of about.com offers a wide array of tutorials for various features of InDesign. They range from the basics to a more advanced offering. No matter what your skill level may be, there is sure to be something new and helpful listed among the entries. However, many of these links may take the user to third-party sites that are less than appealing but the information is still there.
Adobe Evangelists

While not very appealing to the eye, this site still offers a good deal of useful information. The site is separated by links that prompt the download of a.pdf file that has been compiled by an Adobe Expert. The topics range from color to guides and graphics settings. Each of these documents will easily provide the user with a wealth of information. Before reading the document on something as simple as guides, I had no idea the powerful featuers that they held!
The topics include:
Understanding Frame Grids
Dragging and dropping into InDesign
Multiple delimiters for nested styles
