Welcome! Thanks for visiting our site! I handle the advertising for C2 Coding, revise and make the programs for the TI-83+ more "user friendly". I also accommodate the rest of our staff with facilities such as office space and a main computer. If you want a program to be easier to use, e-mail me (in the subject line type "ATTN Red Baron"). If you know someone else that could use our programs or web help . . . please . . . tell them! We appreciate the traffic! Thanks!
