1. We are expecting some quotes from a professional this week -- Erik has more info.<br>2. All we need is some opening and intercom hardware because (a) George will have someone install it for us and (b) Marc/Erik/Andrew/Dan/Jae/Myself/andNowSusan/AnyoneElse are interested in making the proper interfaces and getting them working all together.<br>
3. I'm working on making sure access is provided as much as possible in the mean time, coordinating with Jenny/Felicia. <br><br>// Matt<br><div class="gmail_extra"><br><br><div class="gmail_quote">On Mon, Nov 19, 2012 at 3:06 AM, Susan Werner <span dir="ltr"><<a href="mailto:heinousbutch@gmail.com" target="_blank">heinousbutch@gmail.com</a>></span> wrote:<br>
