Bringing this thread back from limbo!
Much has changed since 2008. For instance, St. Louis has a hackerspace (Three if you count the two splinter groups).
While Arch Reactor appears to be the de facto group in St. Louis area, it is not without its flaws.
I propose a chance for a new meet up. This time in St. Louis County rather than the city. The location will need to be determined by a majority of the people interested. It will need to be near a bus route. (Sorry, St. Charles County residents. Get on board with mass transit and connect with Metro more than just at rush hour and we might consider setting up in your area.)
Surely there are some folks at UMSL, Washington University, Webster University, Maryville University, or even one of the St. Louis Community Colleges interested in holding meet ups or creating a hackerspace that could unify the two splinter groups.
