Anyone knows a program which I could use to transfer items from 1 character to another without using LAN or battlenet?
I use to use Jamella a really long time ago but it doesn't seem to be working at the moment.
Thanks in advance.

Try using Plugy - check out this thread: http://www.blizzsector.net/mods-mod-making/25101-ladder-ubers-plugin-plugy-survival-kit.html

It says ubers plugin, but it's so much more than that. By those who use it (esp for Diablo 2 mods), it's more popular for allowing users to twink (mule) to their other characters. Just read up on installation, and have fun.
