The Hallmark Channel, which will air a two-week "Countdown to Mother's Day" campaign, is setting up a "virtual wall" on its Facebook page (facebook.com/hallmarkchannel) to give viewers the chance to submit testimonials, photos and videos of their mothers.

In addition, the wall, which goes live today, will serve as a forum for military servicemen and women abroad to send a message of love and thanks to their own moms, or for military moms to send love back home to their families.
