Some ideas and comments:
I haven't been down there yet. For the most part because Thursday evening conflict with classes I'm taking at PSU. For the next month or two I can only make it on the Weekends (Fri-Sun) and Monday.
Once I do make it down there, and if the space is acceptable, I'm will join as a member. I like the idea of free membership, or even preliminary free memberships, so people can check out the space over a period of time before committing money. Still, at the onset, I'm willing to throw down at least $20 a month. I am also willing to put in man-hours if help is needed with the space. I like doin' stuff.

Speaking about doin' stuf, the my main interests in joining a space like this are centered around being able to do stuff that I can't do alone. Things that either require 1) skills I don't have or 3) equipment I don't have or 4) ideas I don't have. Communities like this, to me, are awesome, because when done well, can provide skills in the form of teaching/learning and collaboration (skill-share), equipment in the form of sharing or communal, and ideas in the form of "know-how," "blind spot" filling, and opportunities to participate in things that I wouldnt have came to my mind on their own.
Otherwise, why participate in a community, I could do work at home in my basement or garage.

Regarding getting folks interested. A few ideas. Participate in meetings, groups, events, yadda yadda yadda, that share similar interest and invite & broadcast from there. Same thing with other mailing lists. (Examples: PDX Timebank, the diff programing groups around town, maker-lab, cyborgcamp, mobile portland, Research Club, etc) Get featured in related media around town. (Silcon Florist, Solid Liquid Air, Strange Love Live, etc) I like the flier idea as well. Was Free-Geek mentioned?

Lastly, talking over the space with a friend of mine...in regards to it being used for group meetings. He said he visited the space and it wasn't really set up to be easily used that way. Is there anything that could be done about that?
See ya,
