We suggest you may want to contact the Events Page co-ordinator via Contacts (top right) before finalizing the date of your event, to make sure it doesn't conflict with a neighbouring event.
New UK Events must include a contact number. They will not be published without one. If no one wants to provide their own personal number, why not think about getting your Event its own number. In these days of 99p sim cards & £10 mobiles it's viable, & it can be passed on to another committee after your Event. Submission Guidelines
