Percy, Eli Adam, Tanya Haddad.
== OSBridge hack-a-thon ==
Proposed for one night of the hacker lounge. They would want a commitment at
least a week before the conference starts. We can use the hacker lounge and/or
a classroom for our monthly meeting. This was generally agreed to be a good
idea.
Science on a Sphere is having a hack-a-thon on Tuesday, so if anyone is
interested in attending that and having stuff up on Wednesday, you should
totally do that.
Wm proposed a TileMill hack session, having people do map building hacks.
Other suggestions? Mele doing OSM introduction presentation?
== Presentation ==
Garlynn presented on Calthorpe's Urban Footprint planner, which was really cool.
== Unconference Report ==
Wm says the conference was lightly attended, but high quality. Rob says that
GIS in Action seems to have been less well attended as well. Stamen is
reported to have won the Basemap Smackdown.
== Misc ==
Wm has a free ticket to Open Source Bridge for a deserving party, and will
give it to said person.
People agreed that getting a variety of t-shirts from OSGeo to wear
at OS Bridge and other conferences. Percy wanted to know if people could
keep them, and Eli said they could if they wanted to.

FOSS4G updates were given, briefly.
We agreed to do a November meeting, and a tentatively a December meeting.
== Announcements == 
* OpenStreetMap Edit-a-thon hosted by Mele, October 19th at Urban Airship. 
* FOSS4G theme and promotion, on the FOSS4G list I'd like to start a brainstorm about FOSS4G theme (someone suggested 'User focused' - similar to 2009 in Sydney) and promotion of the conference of that theme as well as Portland and Oregon. What makes Portland so Portland? Flipping through a recent copy of Momentum magazine, I noticed Kinn Cascade Flyer bikes (made is Portland), the produce pedaler, and North St bags (also made in Portland). These are just a few things. Making a list of these, we can then tie into them as appropriate in promotional material.
