The 3RDC Core committee met prior to the general membership meeting on

Jeff is doing a great job with investigating the requirements to become 
incorporated. Jeff explained the application procedure. He also provided us 
with examples of what information our by-laws will need to contain. We also 
talked about how we are going to raise funds to cover the costs necessary 
for the various applications.

Lou is looking into obtaining a company sponsor to distribute mail to our 
members.

steering committee members.

the results with us in an upcoming meeting.
