Note that VisForVoltage contains an Event Calendar arranged by day and month and year. It is best that event announcements be posted on the calendar.
It is best that the EV Events forum be used to discuss Events.
To make an event announcement in the calendar, click on "Create Content / Event" and fill in all the boxes. The boxes include a start and end day for the event. Make sure to fill in at least the start date, the end date is important for multi-day events.
