What does sfilter mean? How do I control the seek ads I see?

'Sfilter'  is a variable you can set to control which Seek ads you will see. It is useful when you are getting too many seek ads on your screen, on your Seek Graph, or when the sought list is too long.

"help sfilter" will show you all the different parameters but here are a few examples:
set sfilter rb   -- show only rated blitz ads.
set sfilter -c-B -- don't show computer ads, and don't show Bullet.
set sfilter n-s  -- show only ads from seekers within 200 rating points of my rating, and don't show standard time control ads.
set sfilter sb   -- This WON'T work! It will only show an ad if it is both standard and blitz, which is not possible.
set sfilter -w-B -- This will show all the standard and blitz ads, because it shows all ads that are NOT wild or bullet.
