Welcome MillionCalcs! We hope you enjoy your stay here.
Omnimaga, overall has grown significantly in the last few years, perhaps why it keeps showing up on Google Search Results. And as well as cemetech.net, Omnimaga.org is a major calc community hub for the TI-84+, and also has lots of TI-nspire programmers too. There are also some Prizm/Casio programmers. I used to program on Casio calculators myself.
Enjoy your time here, and have fun!
