If you have Thunderbird installed for email, its optional Lightning
Calendar has a versatile events feature which has a reminder feature.
Something I like about it: when the reminder box pops up, I can choose
to Dismiss it, or Snooze it for a specified amount of time. A reminder
can be very descriptive (can include Location for an event, attendees,
attachments, it accepts a lot of text in a Description box...), or could
have just a title with a day/time.

two replies in the PLUG digest but not the original message from JJJ. No
it isn't in spam quarantine and yes I checked the Trash folder.)
