Thanks for the replies [ sorry for being so dumb]

B&R - yes they are our TB's we want to track. We have put some TB's out in Canada last year and initially we got notification when they moved on but now we no longer hear about them - so periodically I do a  'find trackable' to find out what is happening to them. This was why we wanted to put these new ones on a watch list [ one especially as it was a birthday present to my husband - TB79JJD - Pitts Special]

Griff Grof - we have never got the message that you have on the example page you sent me  'watch this trackable item' so I must have been on the wrong page Doh! I'll have another go today.
Thanks for all your help Jenny
