I think it would be a cool idea to be able to edit your own calendar to add in special dates in torn such as birthdays/anniversary's/chains ect
and on them days you will get a event to remind you.
Not sure how feasible this is, but it would certainly be helpful for marking when to start stacking, when a faction is changing specials, etc.
The notepad can fo the same thing, just without the visual of upcoming reminders. For this reason, I think Ched would shoot the suggestion down. Though eho knows, maybe Chat2.0 has personal calendars planned.
