Someone over at the TKTS Booth in Downtown Brooklyn sent this to me:

I wanted you to know that for the TKTS Booth in Downtown Brooklyn there is a daily email blast called TKTS Today that we send around 11am, the time TKTS Downtown Brooklyn opens from Monday – Friday, saying what shows on Broadway, Off Broadway and in Brooklyn are available. 

We offer this to people who live in work in Brooklyn, and you’re blog has really helped me learn a lot about Brooklyn since we opened the booth there (I’m from Queens, so what do I know?)  The TKTS Downtown Brooklyn  booth  is at 1 MetroTech Center at the corner of Jay and Myrtle.

Here is the link to the place for people to sign up.
