(4) All events of a particular type, eith all the people involved in them
(5) Events relating to anyone who was a member of a particular group or

text in any field in any record (there is a limit, imposed by disk space). My
diary takes 40 Megs.
Relational databases have "Memo" fields or something similar for storing
large amounts of text.

A much better version of the VB program has been uploaded to the Files section of this group's website. It's called "GENEVENTS2"
It can be used to store literally anything that one could ever imagine because users can add their own categories for Events, Facts or Relationships between people.
Any date system can be used, but if full automatic sorting is required for print-outs, then we need to use the YYYY,MM,DD format. If however some dates are not in the correct format (and order in a printout) then they can be simply re-positioned by Copy/Paste in the print-out panel.
If "Connected People" are required for event descriptions, then just click on their names and they will be automatically inserted.
If Sources of information are required for events etc, then they simply need to be entered with the event.
The program has a concise Help section in the Menu, so most questions will be answered there.
This latest version should make it easy for anyone to create a database with a SUITABLE 5.5 Gedcom and start seeing future potential or current weaknesses with the system.
