I did a major update only recently for Anytime Orienteering. Should be available on the website.
It's more helpful if mapping updates are given to the people who look after the map database. For Anytime Orienteering you have to register to get maps, you can't just get them direct off the website.
I just gave it to the person who got me to do the job. I have no idea what happens after that.
I noticed half a control plate from the anytime orienteering lying on the ground somewhere on the compass course. Couldn't work out where it had come from.
Probably from the other half.
