Somnus is correct, muling is the only means of sharing items; sorry mate. If you have the Median XL Launcher, you should be able to run two instances of Diablo for this purpose, if I am not mistaken. Just, don't leave your mule in there for too long, or carry on while that character is around. It can get banned temporarily, or permanently after repeated instances; if I am not mistaken. Also! Welcome to Median XL!
