Would anyone have an idea about how to attach a file to a calendar event in iCal? - That is, I want to either attach an alias of a .pdf file (an article for a reading group, for instance) or a link to the file on my harddrive. Is this possible? It seems straightforward and so I feel I must be missing a simple method to do this, but ... I just can't figure it out. Any help would be greatly appreciated.
