Option to filter emails sent for "Collections For Sale" to only your interests.

I'd like to see an option for the "Collections For Sale" to allow for us to select those collections we are interested in. For example, I am only interested in seeing collections that go up for sale for Video Games and not Cards or Comics. So I get tons of emails for stuff I'm not interested in.  Also, I've noticed twice over the last several months that the emails seem to "turn off" automatically and I have to go back into my settings on the site and turn it back on. Thx.
