There are some useful wang aliases
here.
I tried using the one you posted and got this response from Mafia after typing wang into the CLI: Refreshing stash contents...

Returned: void
It sounds like it made the wang but borked the using of it.
Edit: of course. seconds after posting this it manages to use the wang. Any clue what caused the "Returned: void" message and the delay? To refresh your memory the alias I used was "alias wang => ash retrieve_item(1,$item[wang]); string name; if("%%" == "") name = my_name(); else name = "%%"; string page = visit_url("curse.php?action=use&pwd&whichitem=625&targetplayer="+name);"
