PostNuke. AGAIN.

[ismgr]

PostNuke 0.726
Yellow Dog Linux 3.0 
Apache 2.x
MySQL 3.23.54
PHP 4.2.2
 
 I was wondering if I could get a few quick answers, if a quick response is 
available. 
 
 1. Is there a PN module that will run calendar events that has some type of 
mail-based notification system integrated? I have PostCalendar installed and 
working, but it has no provision for notification that I could see.
 
 2. How can you allow users to post news articles immediately?
 
 3. Is there any provision in any PN modules to sync to a PDA?
 
 Thanks!
