Hi.  I need to trigger an auto email when specific type of Event is scheduled for a lead.  I am unable to write a worflow rule to accomplish this because the lead object workflow rules cannot see the Event fields.  To get around this I believe I need to copy the Event Start date/time for this specific type of Event to a Lead custom field.  I can then trigger a workflow rule to send an email to the lead based on that Lead custom field being populated. 

Does this seem to be the best way to accomplish this?  Can I get some help writting the Apex trigger?  Thanks!
