Here in Austin, commercial brokers like to use this e-mail list to broadcast their haves and needs to the brokerage community.  I'd say that there are anywhere from 100 - 200 emails sent out every day, so naturally it can be tedious to sort through them all.  People send everything from executive suites needed to clients looking for 100,000 SF. 

Last week I sent out broadcast for a VERY small deal.  1 - 2 offices for a U.S. Senate candidate, looking for a 6 - 9 month lease.  The commission here was hardly worth anything, but it was more a favor than anything else.  Imagine my surprise, when on the road to Arkansas (to see my Longhorns lose to the Razorbacks), I had over 30 responses by e-mail or phone.  WOW!  Landlords are scared, and looking at anything to get more cash-flow.  I've talked about this with some other guys, and it is truly a great time to be a tenant looking for space, you can get some really great deals.
