It's not really the done thing here. Nothing was done for my 10th Anniversary of High school and I don't know anyone older or younger than me who has had a school reunion. My school was knocked down in 2009 (6 years after I left). We were all invited to the school for a look around and a concert which I went to. Plus I wouldn't be comfortable saying I live on benefits now and have done so for 6 years :-(
