You don't need money to set up a computer group. All you need is space, computers and volunteers.
Volunteers can be recruited from businesses (see BT IT Ambassadors or other company schemes, or regular folks in your locality) and space can be obtained through writing to businesses, using a school's IT suite, or your council's offices.
