I should have said that Sister cards are sometimes created "Unexpectedly"
instead of "Automatically".
Some card Types have button to create a Sister card, the Cloze type does not.
Sisters sometimes appeared like Ghosts with no appearant reason.
But, one 'stumble-upon ..." at a time, I'm discovering the rules. ( No
offense, Peter; I know you have no man power to spare; but you can create a
Wiki-mnemosyne to enlist volunteers. )
My latest "Stumble-upon" was your note in a forum: "Sister will be created
'tomorrow' (BTW , I wish the Automatic Sisters were created 2 weeks or so after
the Main card; why? bcs they :
1. interfere with learning
2. distort the SRS schedule
... bcs they are PROMPTS, hints for each other (during the Learning phase,
when they are scheduled too 'close' to each other ).
Thank you for the ALWAYS timely responses.
PS. One 'drawback' of your expeditious responses - the Volunteers don't have a
chance :-) to answer the questions.
