Harbor Workspace proposes a lunchtime skills exchange for 20 members next Thursday. Budget ceiling: €120. Room capacity: 16. Food quote: €8 per person. Member interest has not been measured. No room has been booked. Desired outcome: members share one practical technique. You can change format or attendance, but not the budget.
