Ticalc.org: A huge website with all the info you could ever know on every TI graphing calculator, and the largest (and most popular) file archive of all the TI sites.

Calc.org: Another big TI website with tons of info and programs for all things TI. Formerly called Dimension TI. And by the way, Adam (the webmaster) is also a Rhode Islander, like myself.

PsychoCorp: Hilarious website that's a spoof of a TI software development company. The Diary is the greatest thing in the world. Classic.

TI-Calculator FAQ: Frequently-asked-questions on many aspects of TI calculators and programming.

Computer Stupidities: Hilarious site. Go here.
