Rather than re-inventing the wheel here....iShowServices include a show diary for show organisers to input their dates and for agility competitors to check what's on when.
This is a free service to all types of agility show, be it Kennel Club, UKA, BAA and any other independent shows.
Show details input into the iSS Show Diary are published each month in the Voice.
