TI's e2e portal

TI has a engineer to engineer forum here: http://e2e.ti.com/ forums this allows folks to:
a) Get a direct and quick answer for a technical question
b) lookup and search for old solutions which might help current problems one might face.
Some of the interesting forums are:
Code Composer Studio
OMAP Application Processor
Power Management IC such as TWL5030 TPS derivatives

it even allows you to have a email notification and bunch of usual stuff..
