Greg is right about Facebook. There are many Missoula community organizations on there that I am a fan of. The group that seems to use the medium to its fullest potential is the Poverello Center. You can become a fan of them or just go to their page to see how they use updates and links to get their message out. Also try newwest.net. Either advertise on there or write a few articles on the same subjects we're discussing here.
The Saturday markets are also coming up soonish. That would be an excellent place to set up an informational table. Basically, you would have your entire audience for the Missoula forum concentrated in downtown every Saturday. Either you could place your table in one of the farmers' markets, the people's market, or on the sidewalk so that people can stop and look as they walk between each event. There is also a farmers' market on Tuesday evenings, I believe. This market seems a little smaller than the one on Saturday and I haven't noticed anyone with a non-food table, but it couldn't hurt to try.
There are also fairs at the university; career fairs, craft fairs, etc. It was at these events that I first learned about MUD. At that time it seemed like their organization was just starting and now they seem very influential in the community. A fair at the university center was also where I first heard of PEAS farm. Aside from the fairs, the UC keeps a few tables available at all times for people with pamphlets, posters, and issues or ideas to talk about. You might want to look into that. I'm not sure if you have to be a student organization to get one of those tables.
You could hold your own manageable event or co-organize one with a more established Missoula entity. Then list it in NewWest events, the Indie's event calendar and maybe do a little write up for each of those publications. Whether or not you decide to co-organize an event, it's probably a good idea to connect with some of the groups in town who have similar ideas. Missoula, as you probably know, functions kind of like a small town and has a great sense of community involvement. Word of mouth can work wonders. So can mutual support. Such a good value!
Well this might be a long list of things. I was sort of brainstorming as I typed. Hope it helps. It shouldn't be too difficult to find an audience for this site in a place like Missoula.
