For permanent mesages, please use the "Yahoogroup" message board. You can either send an email to grangepark@yahoogroups.com or - if you are a member of Yahoo - use the "Post" link on the Group.
Messages in this forum will eventually disappear, whereas the Yahoogroup is permanent..and you can attach pixtures too! If you can't manage to put a message on the Yahoogroup, then leave it here and it will be transferred across.
