I'm not associated with TIES, but here's what I found:

http://www.ties.k12.mn.us/

TIES apprears to be a colaboration between 40 school districts in 
Minnesota, to provide "cutting-edge software applications, hardware and 
software, Internet services and professional development."

It appears that Brian Dolan-Goecke is employed at TIES, and they are 
graciously allowing him to hold meetings there on Saturdays. The building 
is located at 1667 Snelling Ave. N., St. Paul, MN 55108 (at the 
intersection of Snelling and Larpenteur Avenues).

For directions, see http://www.ties.k12.mn.us/Find_TIES.html

Hope to see you there,

Matthew
