Please don't post links to Nspire OSes unless they're hosted on the TI site itself:
2) Not provide links to copies of those files, either in public or PM, unless they are directly hosted somewhere on TI website (which I doubt). Either tell the member who requests them to search for them himself or find a different way to provide him the links.
If you want OSes compatible with Ndless, a list of them (all hosted by TI) is available
here.
