I am an 11-year-old student who has written before to these columns, appealing for stamps to help the Society for the Prevention of Cruelty to Animals (SPCA). All I ask of readers is that if you get mail from anywhere in the world, just tear off the stamp (I accept used and unused stamps) and send them to me at the following address - 16B Kennedy Heights, 10-18 Kennedy Road, Mid-Levels, Hong Kong. I will make sure they get to the SPCA. The organisation sells them to collectors and with the money it makes can help more abandoned animals. MARC JEKER Mid-Levels
