after a search on Thunderbird, Calendar and here (Seamonkey), I haven't found any solution, so here is my problem :
- in Seamonkey Lightning, when I create a new event, its confidentiality is automatically set up to "public"
- I would like to have *by default* all new events set up to "show only date and hour"
- this way, when I share a public link to my calendar, people can see when I am busy, but not on what I am busy

I figure there is maybe an about:config file to tweak?
I am on windows 10, Seamonkey 2.49
Any help / thoughts appreciated
Sincerely,
Doc
