Hi Laura,
You might want to join openeegbusiness at groups.yahoo.com, I'm the
moderator of this list. On this group, we're trying to assemble a team of
people to take the OpenEEG meter to the next level, get some units
constructed, get a legal and marketing team together and really bring this
project to the public.
Yours,
Steven.
