Future development and support for MR/2 ICE for OS/2 and Windows will be donation-ware, maintained on a best efforts basis. To register MR/2 ICE for OS/2, you must donate a minimum of USD $35 for a one year subscription to PetSmart Charities online, and forward a copy of the email receipt with the headers intact.
Your registration code entitles you to upgrades and support for one year on a best efforts basis. A registered version will work forever, regardless of subscription status; without renewal of the annual subscription, an individual will not have access to newer versions or support.
