We need to have a procedure to give new users in the company a default set of Sametime groups to start chatting with their colleagues. Because the contactlist is still in the OLD binay:data:base64 format, you cannot simply add users' groups/contacts in a mongo-collection-way. You have to build the contactlist and decode it in BASE64 format. But there is also another way to do it.
