BBNC allows for participant attribute merge fields in email blasts. There's no way to specify which event, however. Since similar events could share attributes, this can be a problem. I tried globally changing the attribute category (from EventName-Info to EventNameYear-Info), but that's not possible, since Attributes field only offers "Add" or "Delete", but not "Replace". I also don't want to change the field name in Configuration, since that would affect all events sharing the attribute. Back to export/edit/import for me...
