[Evolution] threading help

[Duncan Lithgow <duncan lithgow-schmidt dk>]

Hi there, I don't know who this is for but I just wanted to mention that
the word 'thread' or 'threading' can't be found in the help files.
Because evolution has this option in a different place from Kmail and
thunderbird it took me a while to find.

Also, how can i teach evolution to ignore certain threads, and notify me
of new mails in threads i have collapsed?

great program by-the-way
