I see the multi quoting tool as a facility for making posts that group together several related quotes that need one or more related answers.
When I first turn on the computer and look at the forum I've no idea how many posts I might rely to.

It's not as if it cost you anything.
And I've heard vastly more complaints about people making long posts than I have about them replying to posts separately. I've only ever seen two of the latter, both from you.
