FARGO (AP) - Some North Dakota outdoorsmen say Microsoft Corp. is linking one of its new programs with an anti-hunting organization, and they are not pleased.

The Humane Society of the United States is one of 10 organizations that will receive donations from the software giant through its "i'm" initiative launched in March. Computer users who join the program are asked to select a cause-related organization to benefit from donations generated from their conversations on Windows Live Messenger.

Microsoft, sharing a portion of the program's advertising revenue, will make a minimum $100,000 donation to each of the 10 organizations during the first year of the program.

The U.S. Sportsmen's Alliance already has asked Microsoft to abandon its affiliation with the Humane Society, the nation's largest animal protection organization.

Chris Hustad, owner of Nodak Outdoors, an online hunting and fishing magazine, and Mark Mazaheri, an avid outdoorsman from Fargo, now are encouraging North Dakota outdoorsmen to voice their disapproval with Microsoft headquarters in Redmond, Wash., and the company's campus in Fargo.

"We would like to make Microsoft aware that we do not support their endorsement for this particular cause," Mazaheri said.

Don Morton, site leader of the Microsoft campus in Fargo, said he expects the company to issue a response Monday.

Michael Markarina, executive vice president of the Humane Society, said the organization does oppose trapping but that the only hunting the group objects to is unsporting types such as canned hunts inside fences. He said the society has no position on fishing.

"We have 10 million members, and you don't build that type of support unless you have a mainstream mission," Markarina said.

"We believe many sportsmen agree with our position," he said.
