Hey everyone, ok i am not new to mac, been around the block of sectors many of times. here is my dilemma. In the old system 10.3.9 We used to able to make an alias of folders to share calendars, itunes, photos, Basically anything my creating an alias of a folder and swapping it out in other users in the same computer. Now with 10.6 I can't figure out a damn thing. I have tried folder sharing and giving permissions to other users, and then tried alias folders, Nothing is working PLease help
